IQS626

Key features :

• Highly flexible 14-channel ProxFusion®
• Each generic channel can be configured with three different types of external connections or one of two internal options.
• 8 external sensor pad connections:
  • Self/Mutual-Capacitive sensors
  • Self/Mutual-Inductive sensors
  • Dedicated reference sensor for environmental / mechanically sensitive designs
• Internal sensor option:
  • Hall-effect sensor
  • Serial scanning (Single ProxFusion® engine) – up to 8 time-slots
• Built-in basic functions:
  • Automatic tuning
  • Noise filtering
  • Differential measurements (reference channels)
  • Debounce & hysteresis
  • Dual direction trigger indication
  • Linearization of measurement data
• Built-in user-interface options:
  • Trackpad (2×3 or 3×3 projected trackpad setups) with:
    • 2-dimensional coordinate output

Specification:

• I2C Interface with IRQ (RDY) line.
• Event mode (including reduced interrupt options: blocking & hysteresis)
• Assign a touch flag state of any channel to a dedicated GPIO (default: active low, open-drain).
• Dedicated address selection pin.
• 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

Applications :

• Use in mobile devices and wearables for small integrated touch screen/area navigational control
• Wear detection and combination sensor uses
• Touch area coordinate & multi-button designs
• Low power wake-up buttons / proximity
• HALL dock detection
• GUI trigger and GUI control proximity detection
• Electronic keypads or pin pads
