AH3372
HIGH VOLTAGE HIGH SENSITIVITY
HALL EFFECT UNIPOLAR SWITCH
Description
Pin Assignments
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
3 OUTPUT
design has been optimized to operate over the supply range of 3.0V

to 28V. With chopper stabilized architecture and an internal bandgap
1 VDD
regulator to provide temperature compensated supply for internal
circuits, the AH3372 provides a reliable solution over the whole
SC59 and SOT23
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
(TOP View)
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

SIP-3 (Bulk Pack)
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.
