AH1808
HIGH SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH
Description
Pin Assignments
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.

SC59
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.

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 VDD of 7V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to
operate the device at the absolute maximum rated conditions for any period of time.

Note:
8. When power is initially turned on, the operating VDD must be within its correct operating range (2.5V to 5.5V) to guarantee the output sampling.
The output state is valid after the second operating cycle (typical 150ms).
