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).
