NOT RECOMMENDED FOR NEW DESIGN USE AH1806 AH180N MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description Pin Assignments ( Top View ) The AH180N is a high sensitivity, micro power Omnipolar Hall Effect switch IC designed for portable and battery powered equipment such 3. OUTPUT as cellular phones, PDA’ s and portable PC’ s. Based on two sensitive Hall Effect plates and a chopper stabilized architecture the AH180N GND 2. provides a reliable solution over the whole operating range. To 1. VDD support portable and battery powered equipment the design has been optimized to operate over the supply range of 2.5V to 5.5V and SC59 and TSOT23 consumes only 24µA with a supply of 3V. ( Top View ) The single open drain output can switched on with either a North or NC 1 5 OUTPUT South pole of sufficient strength. When the magnetic flux density (B) GND 2 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 NC 3 4 VDD point (Brp). The output will remain off when there is no magnetic field. SOT553 Features Applications  Omnipolar (North or South pole) Operation  Cover Switch in Clam-Shell or Slide Type Cellular Phones  High Sensitivity  Display Switch for Portable PCs  Single Open Drain Output  On/Off Switch for PDAs and Digital Cameras  Micropower Operation  Contact-Less Switch in Consumer Products  2.5V to 5.5V Operating Range  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 (HBM) > 6KV  SC59 (SOT23), TSOT23, and SOT553 Low Profile Packages  Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  Halogen and Antimony Free. “Green” Device (Note 3) Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant. 2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm antimony compounds.
