AH173

INTERNAL PULL-UP HALL EFFECT LATCH FOR HIGH

TEMPERATURE

Description

Pin Assignments

AH173 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, a comparator to

provide switching hysteresis for noise rejection, and an

output driver with a pull-up resistor (Rpu). 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.
