General Description

The AH478 is a single coil Hall sensor with output drivers designed for brush-less DC motor application.

This IC consists of one H-bridge driver for motor's coil driving and has automatic lock shutdown and restart function relatively.

To avoid coil burning, rotor lock shutdown detection circuit shut down the output driver if the rotor is blocked and then the automatic recovery circuit will try to restart the motor.
