General Description
AH182/AH183 is a three-terminal Hall effect sensor device with
an output driver, mainly designed for battery–operation,
hand-held equipment (such as cellular and cordless phones, and
PDA’s) The total operation power is down to 15uW in the 2.75V
supply.
The south pole of sufficient strength will turn the output on in
SIP-3L but the north pole of sufficient strength will turn the output
on in SC59 package. The output will be turned off under no
magnetic field.
While the magnetic flux density
(B)
is larger than operation point
(Bop),
the output will be turned on (low), the output is held until
B
is lower than the release point
(Brp),
then turned off. The
difference between AH182 and AH183 is that the former
consumes less power than that of the latter in the Hall sensor
operation.
