Product Overview
The AH3382 is a high voltage, ultra-high sensitivity Hall Effect Unipolar switch IC designed for proximity, position, and level sensing in industrial and consumer home appliances. 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 internal pull-up resistors, over-current limits, and Zener clamps for robustness. It activates with a South pole of sufficient strength and remains off for North pole or no magnetic fields.
