The Si7201 is a Hall effect magnetic switch designed for position sensing in battery-powered applications, offering omnipolar operation and low power consumption. It is available in a 3-pin SOT-23 package, with a supply voltage range of 1.71 to 5.5 V and an operating temperature range of -40 to +125 °C. The device features a typical current draw of 400 nA at 5 samples per second, a maximum operating magnetic field strength of less than 1.1 mT, and an open-drain output. Temperature and offset drift are compensated digitally, with sensitivity drift under ±3% over temperature.
