i would love this, i want to learn IC's but its so much easier to just listen to someone explaining it then sifting through datasheets.

I once lost power for over 24 hours. Finally I had to get some power going so popped the hood on my retired police Crown Vic and hooked up a 750W inverter I have. Started it and left it idle. Ran extension cords inside and was able to run lighting and cell phone chargers, and my laptop. It ran like that over 12 hours, burning half a gallon of gasoline per hour. Least efficient 750W generator you can get, but it was nice to be able to get by on a whim. It was funny I went out to it after about 6 hours of idling and it was making a funny burbling noise. I stomped on the gas pedal and got about a gallon of water from each tailpipe. It had filled the mufflers with water and the noise was the exhaust bubbling through it.

In 2004, I attended a course in Montreal given by Microchip on power design and management. During the brake, I went to talk to the instructors and their power engineers. I asked them if they would be interested in designing and making an "Energy Harvesting" chip exactly as you described (BQ25504 ). They looked at me as if I was drunk or crazy! Told me that they don't think its a very useful chip and they would not be interested in providing me with any engineering help! I even showed them a circuit I built that was capturing solar energy from solar cells at night from moon light! Much like your jewel thief, but it would charge a large cap and then, when the voltage was high enough, dump the cap into the battery. But hey... I can show the horse where the water is, but I can't make the horse drink it... Good on you Ti.

Proving that sponsored videos don't have to suck. Good choice by TI and another very interesting video by bigclive.

I remember TI being a _major_ player in the 1970s with IC development, and calculators, etc. Nice to see they are still developing ICs for special applications today. Ray (RODALCO2007) did a video taking apart one of the blinking overhead line fault indicators.

I have a 3 deep cycle batteries hooked to two 100 watt solar panels and a generator for power outages. Internet, wifi and phone run solely off solar. The solar is very generous and I haven't had to start the generator for over 3 years during a power outage. Sadly the cable companies back-up supply only lasts about 8 hours before I loose internet and phone connection. - Northern Ontario in Canada

I live just along the coast from you in Sussex. Christmas 2013 my power was out for 10 hours on 23rd December, briefly came back on, then went down again on 24th December for 68 hours. Despite the power company being advised that we were "vulnerable", (my wife through age, myself through a chronic heart condition), we were clearly low on the priority list and spent Christmas by candlelight (possibly romantic but a tad boring) and without heat (decidedly not romantic)...Owing to both Christmas/New Year, and a wedding anniversary we had two freezers plus a refrigerator full of food, and had food enough to eat, including tinned (heated, as you suggest, on improvised facilities) until the whole damn lot thawed....when the power came back on we couldn't refreeze it and so lost nearly all our remaining food... To be fair on Christmas Day the power company had belatedly offered to pay (in arrears) for any hotel accomodation we could book...as if...at short notice on Christmas Day...and they'd take our pets...yeah right... (even assuming we had the means of paying upfront - we didn't if we were to budget for the rest of the month, and said so).... We fortunately weren't solely reliant on pensions and so managed until the next "payday" came in about three weeks later... Shockingly it took until June 2014 to (a) get the power company to pay the meagre compensation due and (b) provide a letter confirming the power-outage, finally enabling us to complete our claim on our insurance for the food loss...without which our insurers refused to pay up...six bloody months... To compound matters when we eventually managed to get our insurance claim processed the insurers asked us how old our freezers and fridge were, intimating that if it was more than 10 years they wouldn't entertain a claim at all - as if this were somehow relevant to what had occurred...just a small-print get-out clause which they employ if they don't feel like paying out...and of course they had to have that letter and point blank refused to phone the power company for confirmation. In fact if we'd been solely reliant on pensions we could have starved until payday for all any of them really cared. I don't query the power outage itself - nature is what it is and conditions were extreme. I do query the administrative organisation of the power company...worse than poor...scandalous...And as far as the insurers are concerned they're just a bunch of crooks and swindlers...they took my money for years without a claim...but when I needed them most they strung me out for six months awaiting a piece of paper, paid me out grudgingly, then subsequently dramatically increased my premiums to recover the money via the back door...your caring insurers... Ok not directly about power management (something the power company clearly doesn't understand anyway), but it gets it off my chest...this country is broken...rant over...

Wow, awesome that you could get a sponsored video! TI is one of my favorites too, I didn't grow up with them like you, but their datasheets make me incredibly happy as an EE student when I'm doing laboratory work!

I had "The Little Professor" made by Texas Instruments when I was a child. I physically wore it out. I have so many great memories of learning math on that educational toy.

Being on an island does increase your likelihood of losing power, but living in a house with many trees between it and the power substation (2+ miles away) means we have dozens of opportunities to lose power whenever there is wind, ice or snow (briefly at least once a year, sometimes more frequently). The 7 to 12 inches of snow across the county this past December had us without power for 12 hours and without landline phone, internet or cable TV for 30 hours. We've had multiple short outages since then as the power company replaces some of the 7500 volt distribution lines with new wire (after XX repairs, they run new wire) and another three hour outage when a tree fell without the immediate assistance of the weather. That tree was big enough to block a road so the incident got a paragraph in the local newspaper. I have the white LED with magnetic base that you showed as it will stick to the side of the over-the-stove microwave oven and provide light for using the gas burners for cooking (long necked "grill" lighter on the counter by the stove for that). My favorite LED headlight is a generic one that uses three AA cells with the battery pack at the back, similar to the one you showed. It hangs on the knob of the door to the basement so I'll have light if I need to get backup power going after dark. I write post-apocalypse fiction (mostly about families and rated PG/PG13) because the characters in my head keep having interesting conversations ;-) I post the stories on a writers' forum and got "You should publish this" comments about one story - so I did. The ebook sold some 1500 copies in a year and a half (certainly better than I expected) and I used the unexpected income to put together a solar charged backup power system that can run fridge, phone, internet and a few LED lights, and charge phones, tablet, etc for about 20 hours. Considering that the longest outage we've had in more than 10 years is 16 hours, I won't be out in the dark or a thunderstorm getting a gasoline generator started. The solar generator has a 12 volt, 540AH battery bank (AGM batteries from a data center UPS that were replaced by time - start of year 6 of their advertised 10 year life - not by condition, as these test like new batteries) and a 2000 watt pure sine wave inverter, which allows me to power essential items via a 4 circuit transfer switch (installed long ago for gasoline generator backup). Nothing automatic except the sun keeping the batteries charged. We also have light and heat options using much older technology - kerosene lamps and lanterns plus candles for light and a kerosene heater that saw days of service when the controller board on the furnace died and the "3 day" turnaround on the replacement board took 2 weeks (January, overnight low temperatures in teens F). I do tend to run on once I get started - my first published novel was 800 pages...

I’ve have always liked TI data sheets. By the bay, even underground lines have issues like broken insulators. When I moved into this house it was all underground working, yet I was resetting my clocks 10 times a week for short power outages that sometimes were less then a second. Apparently this went on for years, and no one called to complain. Once I convinced the electric company with UPS logs something wasn’t good, the finally decided to look into it. They found a a lone with a broken insulator they was triggering something downline to clamp that looked like short 1 second outages. They had to switch me and a the neighbors on my block to another company for power from some windmill farm. I think it took them a year before they fixed it and switched us back. After that year I would still get the short outages, much less frequent. So I asked them who was providing power before and they refused to tell me, lol. I wanted to switch my house over to the other company for s cleaner more stable AC power.

Hello from Florida, USA - had two hurricanes in 11 months - Matthew and Irma - good luck with yours!

Love your videos. And Merry Christmas.

I spent some time of my many working years in the semiconductor industry, mainly in testing. Data sheets then were found in data books, (choose from analogue, digital, ADC, DAC, special function, power or discrete components). Although we dealt mainly with National Semiconductor, Motorola or International Rectifier, there would always be a requirement every so often for testing of Texas stuff, mainly op - amps and comparators for aerospace applications. TI data books would always provide (along with testing data) test circuits and application circuit diagrams, most useful when designing test circuits, simplifying the test processes. They would be tested in house, usually on an in house assembled, hermetically sealed ceramic package, or sometimes a bare wafer prior to sawing and traying up in anti static trays using a vacuum pick and place machine in a clean room. For reference, the mainstay test machines that used to be used were the Linear Test Systems 2020 16 bit computer based system, otherwise known as the LTS 2020. This was a complete semiconductor test system, designed by Analog Devices in the late 1970s/early 1980s for their own in house semiconductor testing, but proved so popular and easy to use that it was sold widely in the semiconductor test industry at the time. I believe that some modified examples are still in use today. Well worth looking up if you are into old testing technology.

Wow, this is the best description of power factor I have ever seen! Keep up the good work my friend.

Probably the most interesting and informative sponsored video I've seen on KZread.

Cheers for TI and Bigclive. I grew up fascinated with TI chips and calculators, and I had a 99/4A. Somewhere I have one of those TI calcs with the bubble display.

That tiny chip reminds me of one I saw recently, I was admiring the programmable nature of it with lookup tables and a FSM in the device for simple automation. Thought I might get a couple just to play with, then saw the size - 1.0x1.2mm - there's simply no way I can do anything with that. I had to reread it several times, blown away. No way my SharpieCad board etching is getting anywhere near using that thing!

Thank you for explaining about overhead fault indicators! There is a stretch of road here where the power lines have these weird things hanging from them and for YEARS I have wondered what they were. I thought they were maybe some kind of leftover decoration or something to scare birds away from the lines. Now I realise they are fault indicators - I guess the power company must have had enough difficulty with those lines to install some.

Very cool. Thanks, BigClive. I used to enjoy reading through data sheets and application notes from early days of commercial ICs. But now there are so many chips out there, one hardly knows where to start any more. Thanks for bringing some really innovative chips to our attention. More of the same! And brilliant of TI to sponsor someone like you to discuss them on your channel. :-)

Evil from evilution Actually, I would argue that a power outage hardly constitutes a day without power management. Quite the contrary, from the moment the power goes out your available power becomes a very finite resource and, especially with expected long outages, your very activities are inevitably governed by a hyper awareness of power management and budgeting. Even with generators on hand you are still budgeting based upon fuel on hand and how readily, or not, replacement fuel can be procured. I've spent much of my life living either in the path of hurricanes (Florida) or ice storms (upstate South Carolina) where it is not uncommon to go for days to weeks without power after a major event due to the magnitude of damage to infrastructure. You get to be very good at power management since you have to make things last. We have a good sized generator and fuel, plenty of batteries and cooking fuel, and my amateur radio station is powered entirely by a very large battery bank built around golf cart batteries so I am never out of communications with the rest of the world no matter how bad things get. In the future I will also add solar to keep my station batteries charged even without the use of a generator.

I visited the Isle of Man a few weeks ago and it was that rough aboard Mannanan that I think almost everybody on the ship chucked up! I think you need a PhotonicInduction style backup with a 3kw inverter and a couple of big marine batteries!

Ohhhh I would love to visit during race week. Clive that’s on my bucket list, a wonderful place to be.

This was quite an interesting video. It'd be great if you do more random ICs roundups. There're so many interesting ICs out there.

Awesome video. I've been preparing our house for power cuts recently. They aren't common, but when it hits, its bad. I have one of those cheap lights and it goes well. I made some LED lights using my old computer parts.

Being pretty rural (by Aussie standards) we too have "power supply issues". Hence, we have a 10kVA (15hp) diesel standby generator and 100 litres diesel. Power output is good, and waveform maintenance (even under full rated load) is true sine wave. We also have grid-tied solar PV, (which can be conveniently redirected to a stand-alone inverter system, should the need arise), and a few 12v inverters that may be usefully driven of the truck batteries. (We also have heaps of rechargeable LED lighting - portable and "semi-fixed")!

It's quite simple, when is Ampere being drawn, during peak of AC voltage 220v or somewhere before/after that 200v/100v/50v. Means more resistance then (high voltage = low resistance) and that means you don't get full power (resistance limits current), and some of it is wasted due to heat, because, resistance.

I looked up harvesting power from vibrations, and found quite the interesting topic. I found, for example, a module that harvests power using piezoelectric. The device says that it can only bend up to a max of 1 mm where it will crack and become unusable. Yet it's actually harvesting electricity from all of those vibrational bends that happen over time that fall under the 1 mm.

Congrats on 300k!

Well clive, it seems you have arrived at the 300 K Subs for your channel. Good for you Clive ! You've been bearing down on it for a while now. I Lift a Glass in your Honour Clive !

In highschool my chemistry teacher said in the 80s he was contracted by some Burger King franchise to optimize their power utilization to correct for a peak load based billing system they were on. He said a lot of it was testing power consumption of each piece of equipment and timing how long the startup load was, what the idle load was, and what the peak in-use load was. He then devised a startup sequence that look place over the course of an hour or so to offset all the peak startup loads of the equipment. He said it resulted in quite a large savings for them and essentially costed them nothing other than his compensation. Today we could probably come up with something with PLCs and such to stage the startups of everything.

This video is one of the few really good sponsored videos out the in the youtube universe.

Living in San Diego, where we've had 4 inches of rain over the last 14 months, I would have been just as happy to have you film the storm and post that to your channel. I miss real weather.

I was born in 1970, so I remember the Winter of Discontent and the three-day week--power cuts were common, so my parents had torches, candles and a couple of paraffin heaters in the house. It was all a fun game for me, being so young, but I dread to think now how much trouble they'd gone to in order to get all this stuff!

Most of the main chip manufacturers have pretty well designed datasheets, but you can tell TI has a focus on electronics education.

Excellent report, very interesting.

Your videos are great!

in canada we're accustomed to losing power during cold winter nights where transformers stop functioning at -40 Celsius. it's quite fun to bring your home made doodads powered by lithium cells and such

To recall the phase relationship, some folks might try to get you to use the mnemonic "ELI the ICE man": Voltage leads Current with inductors; Current leads Voltage in capacitors" - ELI: E = voltage (emf), L = inductor/coil, I = current; ICE: I = current, C = capacitor, E = voltage

The energy harvesting chip is super cool. It's source for some fun projects for little devices you can leave around your house that occasionally activate with some LEDs or something. Maybe this could be used for a 'hot hob' indicator? Can you get enough power from a few thermocouples?

I made an account with TI & requested a couple sample of the 2 chips for testing. Will take 2 days for approval...but i should get both of the chips pretty soon after that.

Your channel makes much more sense now!

talking of TI, i have some of their first 74 TTL chips with 1966 and other late '60s date codes!

Another great video, clive! I think TI owes you double whatever it is they offered. I didn't know spiked current draw was such a power factor! Though, I quite imagine it looks a lot more sawtoothy than square wave.

Clive, you could always add an on demand water heater that can run on LPG or natural gas depending on what is available on the island. Bosch made a nice unit that did not require power to light the gas burner, instead it had a micro generator that ran off of the water supply. It would charge up a circuit that would fire a spark to ignite the burner. Island life is nice at times but in the winter storms blow in without much warning. I guess I was too used to having Doppler weather radar available most of the times in the states. He in Crete they don't even know what Doppler radar is.

I love this idea, next time we have a massive coronal mass ejection we'll be without for more than a day! So how about a teardown of a solar charger for some proper big capacity battery which you could power a small inverter? Much love

Yep, their microcontrollers are excellent. Though the documentation is not, and nor is the crappy middleware they try to push on you...

On that power harvesting chip, I was missing a voluntary disable input, so the uC/main load could tell it to stop feeding it power until (condition). Because stopping the output circuit is more efficient than feeding voltage to a near zero load that has turned itself off, and feeding the load through a second power switching transistor in the load is less efficient than reusing the transistor that turns off during battery low conditions.

I reckon your 'leccie' is about as reliable as ours in rural Yorkshire, however, we have a choice of generating sets to see us through - Daytime, Brush RS-3 20kVa (makes a bit of noise!), Teatime, Lister 6kVa (not so noisy, and not so greedy on fuel), Night-time, Onan RV4 2kVa remote operated, propane fuelled (low output, fairly quiet, and you can start/stop the engine from indoors). I admit though, that's not really in the spirit of this thread, but we do have a good smattering of LED torches, headlights and lanterns. Somewhere in the darkest recesses of our cabin, there are three DC-AC inverters of various types, and in cold weather, you can't beat a good old "Tilley"(tm) or "Vapalux"(tm) etc. One pint of paraffin provides about six hours burn time (light and heat), depending upon how much pressure in the tank. Even a couple of hurricane lamps are quite handy! For a domestic room light, there's still plenty of scope for an "Aladdin"(tm) model 23, or "Super Aladdin"(tm) No.14 mantle lamp.

Oh, I like this. I'm actually a bit of a TI fanboy. I was designing basically my first every circuit (discounting some blinky lights), which was a KVM switch that also comes up as two USB Hubs and you can switch which Hub the physical devices connect to. This is a ridiculously niche application, so it is understandable this doesn't really exist as a product. However, looking for ICs to accomplish this, I kept finding TI things. They really have ICs for everything imaginable. And their data sheets are simply amazing. Especially since they even give you example use cases. In the end I never actually got it manufactured, since I didn't want to spend the money for a 4-layer board that might not even work. (And prototyping is not really an option, since both HDMI and USB are too fast for breadboards...)

When I was a teen-ager, I built a lot of DIY Electronics. I asked for so many data sheets and engineering samples... I think they knew I was a kid, but they sent the samples anyway. I guess they figure any kid who bothers with learning how to select OP amps is probably worth cultivating as a client, but my father was astonished at what they would send me. I easily would have cost enough to put a down payment on a house to buy all the chips they sent me. I have been thinking about the power factor problem. I think that a lot could be done with power conversation circuits that we will need for solor and battery backup systems. I am thinking something that follows the voltage and current, and uses a cap bank to fix the current waveform by pumping power in and out of the cap bank. When the line power fails, the same circuit could switch modes to be the inverter to run the house. This is basically a parallel inverter with some extra functions.

I do like TI's datasheets. I look at various datasheets all day long and TI's are the easiest to find orderable part number from.

I have the Biolite 2 stove. Cooks using wood and provides electrical power (thermocouple I presume) to charge your phone, provide light (all via a USB port) Works well and is fun to use

Great video!

What's this??? A Big Clive Christmas special?

That power factor correction circuit is magic, literally. PFC circuits normally work by sensing the mains voltage and controlling the input current of a boost converter to be proportional to, and hence in phase, with the mains voltage. This circuit apparently does it without sensing the mains voltage at all, spooky. How does it make the input current sinusoidal at all let alone in phase with the mains voltage without sensing the voltage?

"I kinda like this one because it involves blinking LEDs" Sentences that will never be forgotten!

Looking forward to seeing power banks with the bq25504 in them :D

A day without power management, I thought maybe your missus was out of town. ;-)

Interesting campaign, stay safe!

TI still does good data sheets, along with the older and more respected fabs who still do their own design work. So many of these newer knock-off companies don't give you anything beyond basic electrical/mechanical specs and pinout. No app notes, no example circuits, no recommended design do's-and-dont's. "You get what you pay for" applies on every level it seems!

Proper weather! What's it say about me that I prefer Stormy weather over bright sunny days?

+Wim Widdershins I love the winter storms. Even when I'm out working in them.

Great vid...

To get fast food and beverage warming you should stash some propane away and a camp stove. I've got a LNG bunsen burner, too, which gives 1.5 foot blue flames when run off of propane. Cooked my eggs very quickly!

bigclivedotcom , I am truly surprised you do do not have some sort of whole house power backup. Wind / Solar and or a battery bank. Solar would most likely be poor due to the location, but the wind option should be awesome! That would be a lovely series to share. Your teardown and or build of Solar / Wind Controllers, Chargers, and other kits...

beat the storm by harvesting its kinetic energy!

If ONLY the Chinese would make data sheets like TI does....

In Chinese, or in Chinglish, they're mostly useless. 😧

Not sure if you have any more TI stuff to do but they have some interesting amplifier chips that are finding their way into a lot of very cheap chinese D-Class stereo amplifiers. Might be worth a look? Some even have BT4.0.
