AH1806
HIGH SENSIVITY MICROPOWER
OMNIPOLAR HALL-EFFECT SWITCH
Description
Pin Assignments
The AH1806 is a high-sensitivity, micro power Omnipolar Hall Effect
switch IC designed for portable and battery powered consumer
equipment such as cellular phones, PDA’s and portable PC’s 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 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 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 guaranteed the output sampling.
The output state is valid after the second operating cycle (typical 150ms).
