The Si7201 is a Hall effect magnetic switch sensor designed for position sensing in battery-powered applications, offering low power consumption and temperature drift compensation. It is available in a 3-pin SOT23 package with a width of 2.8 mm, height of 1.2 mm, and length of 2.9 mm. The device operates from 1.71 V to 5.5 V, supports omnipolar or unipolar magnetic field detection, and has a maximum operating point of less than 1.1 mT. It features an open-drain output, selectable sensitivity and sample rate, and consumes 400 nA typical current at 5 samples per second. The operating temperature range is -40°C to +125°C for I-grade variants.
