AH1815
LOW SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH
Description
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.
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 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.
