The Si7201 is a Hall effect magnetic switch with omnipolar operation, designed for position sensing in battery-powered applications. It is available in a 3-pin SOT-23 package and operates from a 1.71 to 5.5 V power supply. The device has a typical current consumption of 400 nA at 5 samples per second and a maximum operating point of less than 1.1 mT. Thermal drift of sensitivity is less than ±3% over the -40 to +125 °C temperature range. Output is open-drain, and tamper indication is provided by the output pin returning to its zero-field level at high magnetic field.
