Product Overview
The AH372 is a single-digital-output Hall-Effect latch sensor designed for high-temperature operation, featuring an internal pullup resistor. It integrates a Hall voltage generator, amplifier, comparator with hysteresis for noise rejection, and an output driver. The device operates over a wide supply voltage range and offers temperature-compensated voltage. It is suitable for applications requiring magnetic sensing, such as rotor position sensing, encoders, speed measurements, and contactless current switches. Note: The AH372 is not recommended for new designs; please use the AH3724.
