AH173 is a single-digital-output Hall-effect sensor with pull-up

resistor 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, and an output driver with a pull-up

resistor (Rpu). An internal band-gap regulator is used to provide

temperature compensated supply voltage for internal circuits and

allows a wide operating supply range. While the magnetic flux

density (B) is larger than operate point (Bop), the OUT pin turns

on (low). If B moves toward release point (Brp), the OUT pin is

latched “on” state prior to B < Brp. When B < Brp, the OUT pin

goes into “off ” state.
