IQS266

The IQS266 ProxSense® IC is a 2×3 projected capacitive trackpad designed for low power mobile applications. This trackpad is perfect to implement on a single sided ITO touch screen for wearables. A self-capacitive channel is used for wake-up which keeps the power consumption in low-power less than 5 uA. Other features include automatic tuning for sense electrodes, internal reference capacitor and internal regulator to reduce total system cost.

Features:

    • Capacitive sensing:
      • Parasitic capacitive load cancellation
      • Fully adjustable sensing options
      • Self capacitive prox channel (CH0)
      • 2x3 Projected capacitive trackpad (CH1-6)
    • Zoom and Low power options for minimal power consumption  
    • Multiple integrated UI options:
      • Proximity/Touch
      • Proximity wake-up from low power using distributed proximity channel
      • Gesture recognition:
        • Swipes: Up, down, left, right (segment indication for left & right swipes)
        • Adjustable swipe length and time limitations
        • Taps: Single taps with segment indication
        • Adjustable tap size and time limitation
  •  Automatic Tuning Implementation (ATI)
  • Minimal external components
  • Fast I2C interface
  • RDY indication for event mode operation
  • Event or Streaming mode
  • Supply voltage: 1.8V to 3.3V
  • Small package size: QFN(3x3) - 16
 

Applications:

  • Wearables
  • Navigational controls
  • White goods and apliances
  • Office equipment, toys sanitary ware
  • Proximity detection that enables backlighting activation (Patented)
  • Wake-up from standby applications
  • Replacement for electromechanical switches and keypads
  • GUI trigger and GUI control proximity detection
  • Electronic Keypads or Pin pads
Let us help you implement your IQS266.
We’ve done it before.
If you don’t believe us test it yourself.
