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  
1 VDD  
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.
