The AH3372 is a high voltage, high sensitivity Hall Effect Unipolar switch IC designed for proximity, position, and level sensing in industrial and consumer home appliances and personal care applications. It operates over a wide supply range of 3.0V to 28V and features a chopper-stabilized architecture for temperature compensation and reliability. The device includes protection features such as a reverse blocking diode, Zener clamps, and over-current limits on the output. The single open-drain output switches on with a South pole of sufficient strength and remains on until the magnetic flux density drops below the release point.
