AH182/AH183
LOW POWER HALL EFFECT SWITCH
General Description
Features

•
•
•
•
•

•
•
Micropower operation
2.5V to 5.5V battery operation
Offset Canceling Technology
Superior temperature stability
Extremely Low Switch-Point Drift
Insensitive to Physical Stress
-40°C to 85°C operating temperature
SIP-3L/SC59 package
Lead Free Finish/RoHS Compliant for Lead Free
products (Note 1)
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.
