Product Description
Product Overview
The AH3572 is a high voltage, high sensitivity Hall Effect Omnipolar switch IC designed for proximity, position, and level sensing. It operates over a wide supply range of 3.0V to 28V and features chopper stabilization for excellent temperature stability and minimal switch point drift. The device offers robust protection with a reverse blocking diode and Zener clamps, and an over-current limit on the output. It is suitable for consumer home appliances, office equipment, smart home, and industrial applications.
