Semtech SX9310

Ultra-Low Power Smart Proximity Sensor for SAR

Add to Watch List

The SX9310 is a capacitive Specific Absorption Rate (SAR) controller. The SX9310 can use two of the three sensor inputs coupled to its smart engine for SAR to accurately discriminate between an inanimate object and human body. The third sensor input can be used independently for standard capacitive sensing.

Features


  • 2.7V – 5.5V core supply (VDD)
    • 1.65V – 2V host interface supply (SVDD)
    • 1.65V – 5.5V compliant host interface (VPULL)
  • Up to three SAR capacitive sensor inputs
    • Patented on-chip smart engine for SAR (Body versus inanimate object detection)
    • Capacitance resolution down to 0.08fF
    • Capacitance offset compensation up to 100pF
    • Integrated RF shield
  • Advanced temperature compensation
  • Automatic calibration
  • Built-in startup proximity detection
  • Ultra-low power consumption
    • Active mode: 70μA
    • Doze mode: 8μA
    • Sleep mode: 2.5μA
  • 400kHz I2C serial interface
  • Programmable interrupt or real-time status pin
  • User NVM for custom default registers values (Standalone mode)
  • Two reset sources: POR and soft reset
