Product Description
Product Overview
The AH3369Q is an AECQ100 qualified, high voltage, low sensitivity Hall Effect Unipolar switch IC designed for position and proximity sensing in automotive applications. It operates over a wide supply range of 3.0V to 28V and features a chopper-stabilized architecture for temperature stability and minimal switch point drift. 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 single open-drain output switches on with a sufficient South pole magnetic field and remains off for North pole or no magnetic fields.
