12V, 3 Hall Sensor, Three Phase Brushless DC motor drive Reference Design based on ROHM Solution

This design consists of a three-hole sensor three-phase brushless DC motor pre-driver and a MOSFET. It is an evaluation board that can drive a brushless DC motor with a supply voltage of 12V (typ) and a motor current of 6A (max) by adding a speed control circuit using a microcontroller to the 3 Hall sensor 3-phase brushless DC motor drive circuit. It requires only one external power supply. When a Hall IC is used, the logic IC can detect the direction of rotation and output a triple multiplier FG.
