The Si7201 is a Hall effect magnetic switch with omnipolar operation, designed for position sensing in consumer and security applications. It is available in 3-pin SOT23 and TO-92 packages, with a supply voltage range of 1.71 to 5.5 V and typical current consumption of 400 nA at 5 samples per second. The device features integrated temperature and offset drift compensation, sensitivity drift less than ±3% over temperature, and a maximum operating point of less than 1.1 mT. Output is open-drain, and tamper indication is provided through the output pin returning to its zero-field level at high magnetic field.
