MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH

Description

Pin Assignments

(Top View)

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 24uA with a supply of 3V.

Output

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.
