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.
The AH173 is available in SIP-3L and SC59 packages.
Features
Description
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.
