AH1815

LOW SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH

Description

Pin Assignments

The AH1815 is a low-sensitivity, micro-power Omnipolar Hall effect

switch IC, designed for portable and battery powered consumer

equipment for home appliance and industrial applications such as

smart-meter magnetic-tamper detection. Based on two sensitive Hall

effect plates and a chopper-stabilized architecture, the AH1815

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 24µW with a supply of 3V.

OUTPUT

V_DD

GND

The single open drain output can switch on with either a north or

south pole of sufficient strength. When the magnetic flux density (B)

perpendicular to the package is larger than operating point (Bop) the

output is switched on (pulled low). The output is turned off when

B becomes lower than the releasing point (Brp). The output will

remain off when there is no magnetic field.
