Description
The AH1802 is a ultra-sensitivity, micropower Omnipolar Hall
Effect switch IC designed for portable and battery powered
equipment such as cellular phones, PDAs and portable
PCs. Based on two sensitive Hall Effect plates and
a chopper stabilized architecture the AH1802 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.
The single open drain output can switched on with either a
north or south pole of sufficient strength. When the magnetic
flux density (B) 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.
