AH180N
MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH
Description
Pin Assignments
The AH180N is a high sensitivity, micro power Omnipolar Hall Effect
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 AH180N
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 24µA with a supply of 3V.
The single open drain output can switched on with either a North or
South pole of sufficient strength. When the magnetic flux density (B)
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.

4. 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
5. 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.
