AH175 is a single-digital-output Hall-Effect latch sensor forhigh temperature operation. The device includes an on-chipHall voltage generator for magnetic sensing, an amplifier toamplify Hall voltage, and a comparator to provide switchinghysteresis for noise rejection, an open-collector output predriver. An internal band-gap regulator provides a temperaturecompensated supply voltage for internal circuits and allows awide operating supply range.When the magnetic flux density (B) is larger than operatepoint (Bop), output is switched on (OUT pin is pulled low).The output state is held on until a magnetic flux densityreversal falls below Brp. When B is less than Brp, the outputis switched off.
