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.
