AH1807

MEDIUM SENSITIVITY MICROPOWER

OMNIPOLAR HALL-EFFECT SWITCH

Description

Pin Assignments

The AH1807 is a medium sensitivity micropower Omnipolar Hall

Effect switch IC designed for battery powered consumer to home

appliance and industrial equipment such as smart meter magnetic

tamper detect. Based on two Hall Effect plates and a chopper

stabilized architecture the AH1807 provides a reliable solution over

the whole operating range. To support battery and low power

applications 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.

The single open drain output can be switched on with either a North

or South pole of sufficient strength. When the magnetic flux density

(B) perpendicular to the package 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.

The AH1807 is available in SOT553 and SIP-3L.
