Si7210 I2C Hall Effect Magnetic Sensors

The Si7210 family of Hall-effect magnetic sensors from Silicon Labs features an I2C interface which enables full configurability of the sensor operate and release points and allows measurement of the magnetic field strength. The Si7210 sensor integrates a chopper-stabilized Hall element, low-noise amplifier, 13-bit ADC and comparator in a single compact package with I2C functionality.

• Digital I2C Interface with 4 selectable addresses
• Optional Digital Alert output
• Optional ratiometric analogue output
• Optional Tamper detect versions
• Wide 1.7 to 5.5 V operating voltage range
• Industry-leading sensitivity allows use with larger air gaps and smaller magnets
• Low power consumption to improve operating life in battery powered applications
• Compact 5-pin SOT23 package
• AEC-Q100 Qualified for automotive applications

The Si720x 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 offers industry-leading sensitivity, which enables use with larger air gaps and smaller magnets.
