H1806
HIGH SENSIVITY MICROPOWER
OMNIPOLAR HALL-EFFECT SWITCH
Description
The AH1806 is a high-sensitivity, micro power Omnipolar Hall Effect
switch IC designed for portable and battery powered consumer
equipment such as cellular phones, PDA’s and portable PC’s to home
appliance and industrial applications such as smart meter magnetic
tamper detection. Based on two sensitive Hall Effect plates and a
copper stabilized architecture the AH1806 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 switched on with either a North or
South pole of sufficient field 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.
