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 superior immunity to stress and RF noise, with built-in protection including a reverse blocking diode and Zener clamps. Its single open-drain output can be activated by either the North or South pole of a magnet.
