MICROPOWER OMNIPOLAR HALL-EFFECT SENSOR

SWITCH

Description

Pin Assignments

AH180 is

micro-power Omnipolar Hall-Effect switch

(Top View)

designed for portable and battery powered equipment such

cellular phones, PDAs and portable PCs. Based on two Hall-

Effect 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.

Output

(SIP-3L)

(Top View)

The single open-drain output switches on with either a north

or south pole of sufficient strength.

Output

GND 2.

1 . Vdd

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.
