AH478 Datasheet - BCD Semiconductor

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.

AH478 Features

* On-chip Hall Sensor Rotor-locked Shutdown Automatically Restart Operating Voltage: 3.5 to 18V High Output Sourcing/Sinking Capability up to 300mA Bi-direction H-type Output Drivers for Single Coil Internal Bandgap Regulator for Temper
