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.
