Description
The AH1883 micropower Omnipolar Hall Effect switch IC is
designed for portable and battery powered equipment such
as cellular phones, cordless phones, camcorders, PDAs, and
portable PCs. Based on two high sensitivity Hall Effect plates
and chopper stabilized architecture, the AH1883 provides
reliable solution over the whole operating range.
To support portable and battery powered equipment the
design has been optimized to operate from 1.65V to 3.3V and
consumes 13uW typical with a supply of 1.8V. To minimize
PCB space the AH1883 incudes a push-pull output structure,
therefore does not require an external pull up resistor, and is
packaged in small low profile SOT553 and U-DFN2020-3
packages.
Either North or South pole of sufficient strength will turn the
output on. When the magnetic flux density (B) is larger than
operate (Bop) the output is switched on. 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.
