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 pre-driver. An internal band-gap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range.
