ETC AH183 Low power hall effect switch Datasheet

AH182/AH183
Low power Hall Effect Switch
„ Features
„ General Description
- 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
- Low profile 3 pin SIP/SOT23 package
AH182/AH183 is a three-terminal Hall effect sensor
device with a output driver, mainly designed for
battery–operation, hand-held equipment(such as
Cellular and cordless Phone, PDA) 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 SIP3 but the north pole of sufficient
strength will turn the output on in SOT23 package.
The output will be turned off under no magnetic
field.
While the magnetic flux density (B) is larger than
operate point (Bop), the output will be turned on
(low), the output is latched until B is lower than
release point (Brp), then turned off that. The
difference between AH182 and AH183 is the former
consumes less power than that of the latter in the
Hall sensor operation.
