SINGLE PHASE HALL EFFECT LATCH

AH477A

General Description

Features

The AH477A is an integrated Hall sensor with H-

bridged output driver designed for brushless DC motor

applications. The device includes an on-chip Hall sen-

sor for magnetic sensing, an amplifier that amplifies

the Hall voltage, a comparator to provide switching

hysteresis for noise rejection, a bi-directional drivers

for sinking and driving large current load. It also

includes an internal bandgap regulator to provide tem-

perature compensated bias for internal circuits and

allows a wide operating supply voltage range.

Placing the device in a variable magnetic field, if the

magnetic flux density is larger than threshold B , the

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