AH182/AH183 LOW POWER HALL EFFECT SWITCH General Description Features AH182/AH183 is a three-terminal Hall effect sensor device with Micropower operation an output driver, mainly designed for batteryoperation, 2.5V to 5.5V battery operation hand-held equipment (such as cellular and cordless phones, and Offset Canceling Technology PDAs) The total operation power is down to 15uW in the Superior temperature stability 2.75V supply. Extremely Low Switch-Point Drift The south pole of sufficient strength will turn the output on in Insensitive to Physical Stress SIP-3L but the north pole of sufficient strength will turn the output -40C to 85 C operating temperature on in SC59 package. The output will be turned off under no Lead Free packages: SIP-3L and SC59 (Commonly magnetic field. known as SOT23 in Asia) While the magnetic flux density (B) is larger than operation point SIP-3L and SC59: Available in Green Molding (Bop), the output will be turned on (low), the output is held until Compound (No Br, Sb) B is lower than the release point (Brp), then turned off. The Lead Free Finish / RoHS Compliant (Note 1) difference between AH182 and AH183 is that the former consumes less power than that of the latter in the Hall sensor operation. Applications Cover detector Speed measurement Home safety Typical Circuit * 2.5~5.5V R L C Output AH182/AH183 Gnd * C is for power stabilization and to strengthen the noise immunity, the recommended capacitance is 10nF~100nF. R is the pull-up resistor, the recommended resistance is 10Kohm~100Kohm.
