Product status

Not Recommended For New Designs

I2C Interface with IRQ (RDY) line
Assign a touch flag state of any channel to a dedicated GPIO (default: active low, open drain)
Special pre-programmed options:

  • Standalone operation on power-up (low-power single button touch)
  • Active high output (push-pull)
  • Timed long-press output (pulse after 5 second touch)

Supply voltage: 1.8V (-2%) to 3.6V

  • Highly flexible 8-channel ProxFusion® controller
  • Each channel can be configured with connections to up to 8 external connections OR one internal option
  • 8 external sensor pad connections:
    • Self/Mutual-Capacitive/Inductive sensors
    • Dedicated reference sensor mode for environmental / mechanically sensitive designs
  • Internal sensor option:
    • Hall sensor
    • Built-in basic functions:
    • Automatic tuning
    • Noise filtering
    • Differential measurements (reference channels)
    • Debounce & hysteresis
    • Dual direction trigger indication
  • Built-in user-interface options:
    • Slider (up to 8 elements each) with co-ordinate output, flick/swipe/tap detection
    • Up to two sliders may be defined
    • Integrated measurement set for capacitance calculation

  • SAR compliance in mobile devices
  • Wear detection
  • Multi-slider & button designs
  • Low power wake-up buttons / proximity
  • HALL dock detection
