AH3564Q
HIGH VOLTAGE HIGH SENSITIVITY
AUTOMOTIVE HALL EFFECT OMNIPOLAR SWITCH Description Pin Assignments The AH3564Q is an AECQ100-qualified high-voltage, high-sensitivity
Hall effect omnipolar switch IC designed for position and proximity
sensing in automotive applications, such as in seat and seatbelt
buckle, steering lock/immobilization, gear stick, transmission actuator
and gear position, HVAC compression, wiper, door/trunk closure, and
so on. To support a wide range of demanding applications, the
design is optimized to operate over the supply range of 3.0V to 28V.
With chopper-stabilized architecture and an internal bandgap
regulator to provide temperature compensated supply for internal
circuits, the AH3564Q provides a reliable solution over the whole
operating range. For robustness and protection, the device has a
reverse blocking diode with a zener clamp on the supply. The output
has an overcurrent limit and a zener clamp. (Top View) 3 OUTPUT

2. GND The single open-drain output can be switched on with south or north
pole of sufficient strength. When the magnetic flux density (B)
perpendicular to the package is larger than the operate point (BOP), 1. VDD SIP-3 (Bulk Pack) the output is switched on (pulled low) and stays on until the magnetic
flux density B is lower than the release point (BRP). Features Applications • …
