This application note describes a driver solution for single winding single-phase BLDC, based on the PIC16F1613 microcontroller. The driver exploits two feedback loops: the inner loop, which is responsible for the commutation control, and the outer loop which is responsible for the speed control. The speed of the motor is referenced to an external analog voltage. Fault detection can be sensed d...
