Data Sheet  
SINGLE PHASE HALL EFFECT LATCH WITH LOCKED PROTECTION AH478  
General Description  
Features  
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. This function  
repeats while rotor is blocked. Until the blocking is  
removed, the motor recovers running normally.
