Q

HIGH VOLTGAE MEDIUM SENSITIVITY

AUTOMOTIVE HALL EFFECT UNIPOLAR SWITCH

Description

The AH3365Q is an AECQ100 qualified high voltage medium

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 AH3365Q 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

switched on (pulled low) and is held on until magnetic flux density B

for North pole fields to or no magnetic fields.
