AH1802
MICROPOWER, ULTRA-SENSITIVE OMNIPOLAR HALL-EFFECT SENSOR SWITCH
Description
Pin Assignments
The AH1802 is a high sensitivity, micropower omnipolar Hall Effect
switch IC designed for portable and battery powered equipment such as
cellular phones, PDA’s and portable PC’s. Based on two sensitive Hall
Effect plates and a chopper stabilized architecture the AH1802 provides
a reliable solution over the whole operating range. To support portable
and battery powered equipment the design has been optimized to
operate over the supply range of 2.5V to 5.5V and consumes only 24µW
with a supply of 3V.

The single open drain output can switched on with either a north or
south pole of sufficient strength. When the magnetic flux density (B)
perpendicular the part marking surface is larger than operate point (Bop)
the output is switched on (pulled low). The output is turned off when
B becomes lower than the release point (Brp). The output will remain off
when there is no magnetic field.
