The Si7201 is a Hall effect magnetic switch designed for position sensing in battery-powered applications, offering omnipolar operation with a maximum operating field strength of <1.1 mT. It is available in a 3-pin SOT-23 package and operates from a supply voltage of 1.71 to 5.5 V, with typical current consumption of 400 nA at 5 samples per second. The device includes integrated digital signal processing for temperature and offset drift compensation, with sensitivity drift less than ±3% over temperature. Output options include open-drain or digital high/low, and it supports selectable sensitivity, hysteresis, and sample rate settings. The part is rated for operation from -40°C to +125°C and is suitable for applications such as reed switch replacement, consumer electronics, and BLDC motor control.
