How to Build a Li-Ion and USB Powered Design with Built-in Charging Part 2

Ғылым және технология

In this video series take you step by step through how to design a circuit that can be power from a USB input (5V) or from a Lithium Ion battery cell and output a regulated 5V. The design includes a battery charging circuit and a circuit that automatically isolates the battery from the power bus when USB power is applied. In part two we go into detail on our boost switching regulator design using Texas Instruments TPS61202 5-V fixed output voltage boost converter.

    Very interesting. As a hobbyist, I always struggle with understanding Data Sheets.

    I have been reading them for many years and still find my self using forums or technical support contacts to ask questions on parts I don't understand

    Can the same principles be used to design a high power circuit, by just swapping the components? I am looking to design a lipo/li-on ups, which will accept a 5volt 6A input, have a 10,000 mAh battery attached to it (that can discharge @ 5 amps). For the output, I am desiring one output capable of 5v/3A (For a raspberry pi 4) and another output of 5v/2A (To power accessories). Can I use the approaches described here, or do I need to keep an eye out for other things? Also, any advice about adding voltage reporting via i2c to this circuit would be amazing! Thanks, and great series by the way! No other video to be found on the whole wide web that dives into this topic, so this is basically gold for me! EDIT: Also, is this circuit safe for the battery and the device if it continues to be plugged into mains, even after the battery has finished charging? Does it automatically stop the battery from trickle charging once full?
