Image of Silicon Labs Si720x Hall Effect Magnetic Position Sensor The Si7201/2/3/4/5/6 family of Hall-effect magnetic sensors and latches from Silicon Labs combines a chopper-stabilized Hall element with a low-noise analog amplifier, 13-bit analog-to-digital converter, and flexible comparator circuit. The Si720x family incorporates digital signal processing to provide precise compensation for temperature and offset drift. Compared with existing Hall-effect sensors, the Si720x family provides a minimum field strength of <1.1 mT sensitivity, which enables use with larger air gaps and smaller magnets. For battery powered applications, the Si720x family offers very low power consumption to improve operating life. The Si720x devices are offered in 3-pin SOT23 and TO-92 packages.

Features
Low 400 nA typical current consumption High-sensitivity Hall-effect sensor Maximum BOP operating point/minimum field strength of <1.1 mT Omnipolar or unipolar operation Integrated digital signal processing for temperature and offset drift compensation		Selectable / programmable sensitivity, hysteresis, output polarity, and sample rate Sensitivity drift < ±3% over temperature Wide power supply voltage 1.7 V to 5.5 V 3.3 V to 26.5 V
Applications
Replacement of reed switches in consumer, automotive, and security applications Automotive position sensing of HVAC valve, head rest, seat track, side mirrors, sunroof, door locks, and other mechanical devices General-purpose mechanical position sensing		BLDC motor control Camera image stabilization, zoom, and autofocus Fluid level sensing, control knobs, and selector switches
