AH478 - SINGLE PHASE HALL EFFECT LATCH
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
