AH1802
MICROPOWER, ULTRA-SENSITIVE OMNIPOLAR HALL-EFFECT SENSOR SWITCH
Description
Pin Assignments
The AH1802 is a high sensitivity, micropower omnipolar Hall Effect
(Top View)
(Top View)
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.
SC59
The single open drain output can switched on with either a north or
U-DFN2020-6
south pole of sufficient strength. When the magnetic flux density (B)
(Top View)
(Top View)
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.

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.
