AH1808
HIGH SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH
Description
The AH1808 is a high-sensitivity, micropower Omnipolar Hall Effect
switch IC. It is designed for portable and battery powered consumer
equipment, home appliances and industrial equipment such as smart-
meter magnetic-tamper detection. Based on two sensitive Hall effect
plates and a chopper stabilized architecture, the AH1808 provides a
reliable solution over the whole operating range. To support portable
and battery powered equipment, the design is 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 be switched on with either a North
or South pole of sufficient strength. When the magnetic flux density
(B) perpendicular to the package 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.
