AH373

INTERNAL PULL-UP HALL EFFECT LATCH

Description

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

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 a 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.

When the magnetic flux density (B) perpendicular to the package 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

is less than Brp, the output is

switched off.
