Product Details

Si720x Series Hall Effect Magnetic Sensors

A range of Hall-effect magnetic sensors from Silicon Labs. The devices combine chopper-stabilized Hall elements, low-noise amplifiers, 13-bit ADCs and comparators to produce high precision magnetically activated switches. The device output changes state if the pre-programmed magnetic threshold is crossed, and the range includes versions with a tamper indication facility. Typical applications include security system magnetic detection, position sensing and revolution counting.

• Industry-leading sensitivity allows use with larger air gaps and smaller magnets
• Low power consumption to improve operating life in battery powered applications
• Low voltage (1.7-5.5V) and High voltage (3.3-26.5V) versions
• Unipolar switching and Latch versions available
• Compact 3-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.
