AH3368Q-P-B

AH3368Q-P-B is an AECQ100 qualified high voltage low sensitivity hall effect unipolar 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, etc. To support a wide range of demanding applications, the design has been optimized to operate over the supply range of 3.0V to 28V. With chopper-stabilized architecture and an internal bandgap regulator to provide a temperature-compensated supply for internal circuits, this device provides a reliable solution over the whole operating range. It is used in applications such as position and proximity sensing in automotive applications, seat position, seatbelt buckle, steering lock/immobilization, gear stick, HVAC compression, transmission actuator, transmission gear position, wipers, sunroof and windows, door/trunk closure, door locks, contact-less switches.
