AH3382  
HIGH VOLTAGE ULTRA HIGH SENSITIVITY HALL  
EFFECT LATCH WITH INTERNAL PULL_UP RESISTOR  
Description  
Pin Assignments  
The AH3382 is a high voltage ultra 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 AH3382 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 internally pulled-up 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.

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 will require south pole to the part marking side  
to operate while SC59 will require south pole to the non-part marking  
side.
