Si720x Switch/Latch Hall Effect Magnetic Position Sensor Data Sheet

PublishTime：2020-08-21

The Si7201/2/3/4/5/6 family of Hall effect magnetic sensors switches and latches from Silicon Labs combines a chopper-stabilized Hall element with a low-noise analog amplifier, 13-bit analog-to-digital converter, and a flexible comparator circuit. Leveraging Silicon Labs' proven CMOS design techniques, 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 offers industry-leading 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, 5-pin SOT23, and TO-92 packages,with power, ground, a single output pin that goes high or low as the magnetic field in-creases, and with the 5-pin parts a disable(sleep) pin, and a tamper output pin. With the three-pin package, tamper indication is by the pin going back to its zero field level at high magnetic field.
