MICROPOWER OMNIPOLAR HALL-EFFECT SENSOR
SWITCH
Description
Pin Assignments
AH180 is a micro-power Omnipolar Hall-Effect switch
designed for portable and battery powered equipment such
cellular phones, PDAs and portable PCs. Based on two HallEffect plates and a chopper stabilized architecture the AH180
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 24uW with a supply of 3V.

The single open-drain output switches on with either a north
or south pole of sufficient strength.
When the magnetic flux density (B) is larger than operate
point (Bop), output is switched on (Output pin is 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.
