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 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.
