AH3368Q  
HIGH VOLTGAE LOW SENSITIVITY  
AUTOMOTIVE HALL EFFECT UNIPOLAR SWITCH  
Description  
Pin Assignments  
The AH3368Q 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/immobilisation, gear stick, transmission actuator  
and gear position, HVAC compression, wiper, door/trunk closure, etc.  
To support 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 temperature compensated supply for internal circuits, the  
AH3368Q 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 South 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 is held on until magnetic flux density B is  
lower than the release point (BRP). The output remains switched off  
for North pole fields to or no magnetic fields.
