Overview: Si720x Switch/Latch Hall Effect Magnetic Position Sensor Data Sheet The Si7201/2/3/4/5/6 family of Hall effect magnetic sensors and latches from Silicon Labs bines a chopper-stabilized Hall element with a low-noise analog amplifier, 13bit analog-to-digital converter, and a flexible parator circuit. Leveraging Silicon Labs' proven CMOS design techniques, the Si720x family incorporates digital signal processing to provide precise pensation for temperature and offset drift. pared with existing Hall effect sensors, the Si720x family offers industry-leading sensitivity, which enables use with larger air gaps and smaller magnets. For batterypowered 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, with power, ground, and a single output pin that goes high or low as the magnetic field increases. With the three-pin package, tamper indication is by the pin going back to its zero field level at high magnetic field. In the 5-pin SOT23 and 8-pin DFN(ing soon) packages, pins are available for both sleep mode activation and separate tamper indication.
