AH182/AH183 is a three-terminal Hall effect sensor device with
an   output   driver,   mainly   designed   for   batteryoperation,
hand-held equipment (such as cellular and cordless phones, and
PDAs) 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.
