DRV8801-Q1: forward and reverse rotation

Part Number: DRV8801-Q1

Hi team,

In the process of forward and reverse rotation, how to judge that it has rotated to the specified position? Will IC have a feedback signal?

BR,

Jimmy

    Hey Jimmy,

    It does not have a precise position tracking, only current feedback via VPROPI pin. 

    For position feedback you'd need an external sensor such as an incremental encoder or hall-effect sensor with a magnet.  

    You could also use a stepper motor instead of a brushed DC motor.  Then you would tell the stepper motor driver the number of steps to advance and the motor would move to that position.

    Regards,
