Overview
AH182/AH183 Low power Hall Effect Switch „ 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 - Low profile 3 pin SIP/SOT23 package „ General Description 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...
