Hall Effect Unipolar switch DIODES AH3376-P-B with Zener clamp and reverse blocking diode protection
Product Overview
The AH3376 is a high voltage, low sensitivity Hall Effect Unipolar switch IC designed for proximity, position, and level sensing. Optimized for a supply range of 3.0V to 28V, it features a chopper-stabilized architecture and an internal bandgap regulator for temperature compensation. The device offers robust protection with a reverse blocking diode, Zener clamp on the supply, and output over-current limit. 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. It is designed for reliable operation across a wide temperature range and is available in industry-standard packages.
