Description
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.
The single open-drain output can be switched on with a south or north
pole of sufficient strength. When the magnetic flux density (B)
perpendicular to the package is larger than the operate point (BOP)
the output is switched on (pulled low) and stays on until the magnetic
flux density B is lower than the release point (BRP).
