Industrial Hall Effect Unipolar Switch IC DIODES AH3376-SA-7 with High Voltage and Low Sensitivity
Product Overview
The AH3376 is a high voltage, low sensitivity Hall Effect Unipolar switch IC designed for proximity, position, and level sensing in industrial and consumer applications. 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 protection mechanisms such as a reverse blocking diode and Zener clamps on the supply and output pins. Its 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. The polarity for operation differs between SOT23/SIP-3 and SC59 packages.
