AH373 is a single-digital-output Hall-Effect latch sensor with internal 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. An internal band-gap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range. To support home appliance and industrial applications, the operating voltage range is up to 20V. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop), output is switched on (OUT pin is pul°C 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 AH373 is available in a industry standard SC59,SOT23 and SIP-3L packages.
