General Description
AH180 is comprised of two Hall effect plates and an open-drain
output driver, mainly designed for battery-operation, hand-held
equipment (such as Cellular and Cordless Phone, PDA). The
total power consumption in normal operation is typically 24µW
with a 3V power source.
Either north or south pole of sufficient strength will turn the output
on. The output will be turned off under no magnetic field. While
the magnetic flux density
(B)
is larger than operating point
(Bop),
the output will be turned on (low), the output is held until
B
is
lower than release point
(Brp),
then turned off.
