Preliminary Datasheet 2.0 FEATURES and FUNCTIONAL DIAGRAM • • • • • • • • • • • Micro-power Omnipolar-Switch Hall Sensor Multiple Sensitivity Options (BOP / BRP): ±33 / ±23 Gauss; Push-pull output ability Chopper stabilized design provides: - Superior temperature stability - Minimal switch point drift - Enhanced immunity to physical stress On board voltage regulator for 1.8V to 5.25V range Push-pull Output (1 mA current ability) Solid-state reliability Wide Operating temperature range: -40 to 150 oC Small package sizes TO-92S, SOT-23 RoHS-compliant material meets directive 2011/65/EU AEC Q100 Qualified PACKAGE ⚫ TO-92S SOT-23-3L APPLICATIONS -Open and Close Detect for Flip/Slide Cellular Phones； -Smart Cover or Dock Detect for Cellular Phones and Tablet PCs; -Cover or Display Switch in Portable PCs (eg: Ultrabook); Digital Still, Video Cameras and Handheld Gaming Consoles； -Door, Lids and Tray Position Switches； -Level, Proximity and Position Switches； -Contact-Less Switches in Home Appliances and Industrial Applications. DESCRIPTION The CH912/CH912L is a high-sensitivity extremely temperature-stable micro-power Omnipolar Hall effect switch IC with internal pull up and pull down capability. Designed for portable and battery powered consumer equipment such as cellular phones and portable PCs to office equipment, home appliances and industrial applications, the average supply current is only 1.62μA at 3,3V for CH912 and 0.92uA at 3.3V for CH912L. To support potable equipment, the CH912/CH912L can operate over the supply range of 1.8V to 5.5V and uses a hibernating clocking system to minimize the power consumption. The device includes a clocking system, a Hall-voltage generator, a small-signal amplifier, a chopper stabilization, two Schmitt trigger, and an output driver controller. The output is activated with either a north or south pole of sufficient magnetic field strength. When the magnetic flux density (B) perpendicular to the package is larger than operate point (Bop), the output will be turned on (pulled low) and held until B is lower than release point (Brp). Two package styles provide a magnetically optimized package for most applications, SOT-23 and TO92S. Each package type is lead (Pb) free (suffix, –T), with a 100% matte-tin-plated leadframe.
