Many industrial applications use external sensors for position feedback and speed regulation of brushed DC motors which are often costly, complex, and take up valuable PCB space.
In this video we introduce TI’s latest brushed DC motor technology, ripple counting; a sensorless approach to motor position and speed control. Eliminating encoders, hall effect sensors, optical sensors, shunt resistors and external sense resistors saves significant BOM cost and board space.
