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.
