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.
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.
