IQS266-0-QNR

Overview

The IQS266-0-QNR is a ProxSense series capacitive touch sensor controller featuring a 2x3 projected capacitive trackpad and one self-capacitive proximity channel. It operates on a supply voltage of 1.8V to 3.3V with low power consumption under 5 uA in low-power mode. The device integrates an internal regulator, reference capacitor, and Automatic Tuning Implementation (ATI). It supports I2C communication and includes gesture recognition for swipes and taps.

Feature Summary

• Integrated 2x3 projected capacitive trackpad with dedicated self-capacitive wake-up channel
• Built-in gesture recognition supporting directional swipes and single taps
• Automatic Tuning Implementation (ATI) for maintaining sensitivity across environmental changes
• Configurable event-driven or streaming I2C communication modes

Applications

• Wearable devices requiring minimal power consumption
• Navigational controls for mobile electronics
• White goods and home appliances
• Electronic keypads and PIN pads

Procurement Notes

Verify the specific suffix 'QNR' against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the QFN(3x3)-16 footprint matches your PCB design guidelines before finalizing procurement orders.

Selection Notes

Select this model when a compact solution for small trackpads is required alongside proximity sensing capabilities. The integrated regulator reduces external component count compared to discrete solutions. Verify that the operating temperature range of -20°C to 85°C aligns with your application environment constraints.

Part Context

This component belongs to Azoteq's ProxSense series, designed specifically for low-power mobile applications. It serves as a specialized interface between user input surfaces and system controllers, replacing traditional electromechanical switches. The series emphasizes minimal hardware overhead through high integration levels.

Replacement Considerations

Check for updated revisions within the IQS266 family. No direct cross-model substitutes are confirmed in public documentation. Evaluate pin-compatible alternatives only if the IQS266 is discontinued, ensuring similar channel counts and interface protocols.
