AH180 MICROPOWER OMNIPOLAR HALL-EFFECT SENSOR SWITCH Features • • • • • • • • • • • • Micropower operation Operation with magnetic field of either north or south pole (omnipolar) 2.5V to 5.5V battery operation Chopper stabilized Superior temperature stability Good RF noise immunity -40°C to 85°C operating temperature SIP-3L/SC59-3L/Low profile DFN2020-6 package ESD (HBM) ＞ 5KV for DFN2020-6 ＞ 6KV for SIP-3L and SC59-3L Lead Free Finish/RoHS Compliant for Lead Free products (Note 1) Green Packages: SC59-3L, DFN2020-6 Lead Free Package: SIP-3L General Description AH180 is comprised of two Hall effect plates and an open-drain output driver, mainly designed for battery-operation, hand-held equipment (such as Cellular and Cordless Phone, PDA). The total power consumption in normal operation is typically 24µW with a 3V power source. Either north or south pole of sufficient strength will turn the output on. The output will be turned off under no magnetic field. While the magnetic flux density (B) is larger than operating point (Bop), the output will be turned on (low), the output is held until B is lower than release point (Brp), then turned off.
