AH1809 LOW SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description Pin Assignments The AH1809 is a low sensitivity micro power Omnipolar Hall Effect switch IC designed for battery powered consumer to home appliance and industrial equipment such smart e-meters. Based on two Hall Effect plates and a chopper stabilized architecture the AH1809 provides a reliable solution over the whole operating range. To NEW PRODUCT support battery and low power applications the design has been optimized to operate over the supply range of 2.5V to 5.5V and consumes only 24µW with a supply of 3V. The single open drain output can be switched on with either a North or South pole of sufficient strength. When the magnetic flux density perpendicular to the package (B) is larger than operate point (Bop) the output is switched on (pulled low). The output is turned off when B becomes lower than the release point (Brp). The output will remain off when there is no magnetic field. The AH1809 is available in SOT553 and SIP-3L. Features Applications • Omnipolar (North or South pole) Operation • Low Sensitivity • Smart E-Meters • Single Open Drain Output • Tamper Protection Switch • Micropower Operation • • Door, Lids and Tray Position Switch 2.5V to 5.5V Operating Range • Chopper Stabilized Design Provides • Proximity and Position Switches • Level Detects • On/Off Switch Digital Contact-Less Switch in Industrial and Superior Temperature Stability Minimal Switch Point Drift Enhanced Immunity to Stress • Good RF Noise Immunity • -40°C to +125°C Operating Temperature • High ESD • Consumer Products Small Low Profile SOT553 and Industry Standard SIP-3L Packages • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) • Halogen and Antimony Free. “Green” Device (Note 3) Notes: 1.
