The HA13557FH has the motor stop detector as shown hatching block. This function is monitoring
the situation of the motor while the motor is running by B-EMF sensing. If the motor will be caused a
misstarting up, the motor will be automatically restarted within 200 ms after the motor stopped. This
function increase the reliability for the motor starting up.
