AH175-PL-B-B

AH175 HALL EFFECT LATCH FOR HIGH TEMPERATURE Description 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 predriver. 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.
