The AH3372 is a high voltage high sensitivity Hall Effect Unipolar
switch IC designed for proximity, position and level sensing in
industrial and consumer home appliances and personal care
applications. 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 AH3372 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.

SC59 and SOT23
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.
