AH1802 Descrizione generale

DescriptionThe AH1802 is a high-sensitivity, micropower, omnipolar Hall Effect switch integrated circuit (IC) designed for portable and battery-powered equipment, such as cellular phones, PDAs, and portable PCs. Based on two sensitive Hall Effect plates and a chopper-stabilized architecture, the AH1802 provides a reliable solution over the whole operating range. To support portable and battery-powered equipment, 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.Features● Omnipolar (North or South Pole) Operation● 2.5V to 5.5V Operating Range● High Sensitivity● Single Open-Drain Output● Micropower Operation● Chopper-Stabilized Design Provides ■ Superior Temperature Stability ■ Minimal Switch Point Drift ■ Enhanced Immunity to Stress● Good RF Noise Immunity● -40°C to +85°C Operating Temperature● ESD> 5kV for U-DFN2020-6, U-DFN2020-3 and X2- DFN2015-3● ESD> 6kV for SC59● Low Profile SC59, U-DFN2020-6, U-DFN2020-3 and X2-DFN2015-3 packages● Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)● Halogen and Antimony Free. “Green” Device (Note 3)Applications● Open and Close Detect for Flip/Slide Cellular Phones● Smart Cover or Dock Detect for Cellular Phones and Tablets● Cover or Display Switch in Portable PCs (such as Ultrabook™)● Display Switch for Portable PCs● On/Off switch for PDAs and Digital Cameras● Contactless Switch in Consumer Products
