AH375

SINGLE PHASE HALL EFFECT LATCH

Description

Pin Assignments

(Top View)

AH375 is an integrated Hall-Effect latched sensor designed

for electronic commutation of brush-less DC motor

applications. The device includes an on-chip Hall voltage

generator for magnetic sensing, a comparator that amplifies

the Hall voltage, and a Schmitt trigger to provide switching

hysteresis for noise rejection, and open drain output. An

SIP-3L

internal band-gap regulator provides

temperature

compensated supply voltage for internal circuits and allows a

wide operating supply range.

3. OUT

1. Vdd

When the magnetic flux density (B) is larger than operate

point (Bop), output is switched on (OUT pin is pulled low).

The output state is held on until a magnetic flux density

reversal falls below Brp. When B is less than Brp, the output

is switched off.

GND 2.

The AH375 is available in SIP-3L and SC59 packages.
