Product Description
Product Overview
The AH3582 is a high voltage, high sensitivity Hall Effect Omnipolar switch IC designed for proximity, position, and level sensing in industrial and consumer home appliances. Optimized for a wide supply range of 3.0V to 28V, it features a chopper-stabilized architecture and an internal bandgap regulator for temperature-compensated performance. The device offers robust protection with a reverse blocking diode, Zener clamps on supply and output pins, and an over-current limit on the output. The internally pulled-up output activates with either a South or North magnetic pole of sufficient strength.
