DESCRIPTION The CH913/CH913L is a high-sensitivity extremely temperature-stable micro-power Omnipolar Hall effect switch IC with internal 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 CH913 and 0.92uA at 3.3V for CH913L. To support potable equipment the CH913/CH913L 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, SO-T23 and TO92S. Each package type is lead (Pb) free (suffix, –T), with a 100% matte-tin-plated leadframe.
