AH1806
HIGH SENSIVITY MICROPOWER
OMNIPOLAR HALL-EFFECT SWITCH
Description
The AH1806 is a high-sensitivity, micro-power Omnipolar Hall effect
switch IC, designed for portable and battery powered consumer to
home appliance and industrial applications such as smart-meter
magnetic tamper detection. Based on two sensitive Hall effect plates
and a copper stabilized architecture the AH1806 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 be
switched on with either a North or
South pole of sufficient field 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.

Notes: 6. Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
7. The absolute maximum V
