AH175 is a single-digital-output Hall-Effect latch sensor 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, an open-collector output pre-

driver. 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 AH175 is available in SIP-3L and SC59 packages.
