Description
The AH3363Q is an AECQ100 qualified high voltage high 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
AH3363Q 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.
The magnetic operating and release polarity is opposite for SOT23
and SC59 packages. The SOT23 and SIP-3 (Ammo Pack), SIP-3
(Bulk Pack) packages require south pole to the part marking side to
operate while SC59 requires south pole to the non-part marking side.
