AH3562Q
HIGH VOLTAGE HIGH SENSITIVITY
AUTOMOTIVE HALL EFFECT OMNIPOLAR SWITCH
Description
Pin Assignments
The AH3562Q 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
buckles, 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 AH3562Q 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 over current limit and a zener clamp.
