AH180 MICROPOWER OMNIPOLAR HALL-EFFECT SENSOR SWITCH Features General Description Micropower operation AH180 is comprised of two Hall effect plates and an open-drain output driver, mainly designed for battery-operation, hand-held Operation with magnetic field of either north or south equipment (such as Cellular and Cordless Phone, PDA). The pole (omnipolar) total power consumption in normal operation is typically 24W 2.5V to 5.5V battery operation with a 3V power source. Chopper stabilized Superior temperature stability Either north or south pole of sufficient strength will turn the output Extremely Low Switch-Point Drift on. The output will be turned off under no magnetic field. While Insensitive to Physical Stress the magnetic flux density (B) is larger than operating point (Bop), Good RF noise immunity the output will be turned on (low), the output is held until B is -40C to 85 C operating temperature lower than release point (Brp), then turned off. SIP-3L/SC59/Low profile DFN2020-6, DFN2020-3 package ESD (HBM) 5KV for DFN2020-6, DFN2020-3 6KV for SIP-3L and SC59 Lead Free Package: SIP-3L (Note 1) SC59 (commonly known as SOT23 in Asia), DFN2020-6 and DFN2020-3: Available in Green Molding Compound (No Br, Sb) (Note 2) Lead Free Finish/RoHS Compliant (Note 3) Applications Cover switch in clam-shell cellular phones Cover switch in Notebook PC/PDA Contact-less switch in consumer products Typical Circuit 2.5~5.5V R L C Output AH180 Gnd Note: 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.
