AH175 HALL EFFECT LATCH FOR HIGH TEMPERATURE Description Pin Assignments 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. (Top View) 3. OUT 2. GND 1. Vcc SIP-3L 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. (Top View) 3. OUT GND 2. 1.
