IQS680-100-DNR

Overview

The IQS680-100-DNR is a proximity sensor integrated circuit manufactured by Azoteq. It supports button input functionality and includes three input channels for sensor connections. The device features two LED driver channels for external indicator control. Communication with the host system is handled via an I²C interface. The component operates within a supply voltage range of 1.8 V to 3.6 V, with a typical power consumption of 10 mA. It is designed for operation in temperatures ranging from -20°C to 85°C. The physical package is a 10-WFDFN with an exposed pad, specifically identified as a 10-DFN (3x3) footprint.

Feature Summary

• Integrated proximity detection capability for object sensing applications
• Dual LED driver channels for visual feedback control
• I²C digital interface for simplified system integration

Applications

• Proximity sensing in consumer electronics
• Button input interfacing for user interfaces

Procurement Notes

Verify the specific suffix DNR against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the exact electrical characteristics and package dimensions required for the design. Cross-reference the component with current availability lists from authorized distributors to confirm active production status and lead times.

Selection Notes

Select this component when a compact solution for proximity detection and button inputs is required. The 10-DFN package suits space-constrained designs. Verify that the host microcontroller supports the I²C protocol and that the supply voltage aligns with the 1.8 V to 3.6 V operating range. Consider the 10 mA current consumption during power budget calculations.

Part Context

This part belongs to the Azoteq IQS series of sensor controllers. It utilizes ProxFusion technology for capacitive sensing. The IQS680 model is distinct from other IQS variants by its specific combination of proximity and button inputs. It is often used in conjunction with development tools like the IQS680EV02-S for initial prototyping and configuration.

Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific model variant. Designers should consult the manufacturer's obsolescence notices or contact technical support for potential pin-compatible alternatives if discontinuation occurs.
