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.

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 Temperature

Compensation

Low Output Switching Current Noise

If a magnetic flux density is larger than threshold B

Operating Temperature: -20 to 85 C

the DO is turned to sink and DOB is turned to drive.

This output state is held until a magnetic flux density

ESD Rating: 3000V (Human Body Model)

reversal falls below B causing DO to be turned to

RP,

drive and DOB turned to sink.

Applications

This IC is available in TO-95 package.
