AH373

INTERNAL PULL-UP HALL EFFECT LATCH

Description

Pin Assignments

AH373 is a single-digital-output Hall-Effect latch sensor with

pull-up resistor for high temperature operation. The device

includes an on-chip Hall voltage generator for magnetic

sensing, an amplifier to amplify Hall voltage, and

comparator to provide switching hysteresis for noise rejection,

and an output driver with a pull-up resistor. An internal band-

gap regulator provides a temperature compensated supply

voltage for internal circuits and allows a wide operating supply

range.

(Top View)

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.
