IQS128-00100-TSR

Overview

The IQS128-00100-TSR is a single-channel capacitive touch and proximity sensor manufactured by Azoteq. It operates within a supply voltage range of 2.5 V to 5.5 V and functions across an industrial temperature range from -40°C to +85°C. The device utilizes a TSOT-23-6 surface-mount package with dimensions of 3 mm x 1.7 mm x 0.9 mm. It supports I2C digital communication interfaces for system integration.

Feature Summary

• Integrates capacitive sensing capabilities for both button detection and proximity monitoring within a single channel architecture.

Applications

• Consumer electronics requiring compact touch input solutions
• Industrial control panels needing reliable proximity detection
• Automotive interior interfaces operating in extreme temperatures

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance documentation prior to acquisition. Ensure storage conditions align with semiconductor handling standards to prevent moisture sensitivity damage during assembly processes.

Selection Notes

Select this component when a single-channel solution combining touch and proximity sensing is required. The I2C interface simplifies microcontroller connectivity compared to parallel alternatives. Verify that the TSOT-23-6 package footprint matches the target PCB layout constraints before finalizing the design.

Part Context

This part belongs to the Azoteq ProxSense family, which specializes in low-power capacitive sensing controllers. The IQS128 series provides a cost-effective entry point for applications requiring basic touch and proximity functionality without complex gesture processing capabilities found in higher-tier models.

Replacement Considerations

Check for end-of-life notifications as availability may be restricted. Evaluate IQS228 variants for enhanced feature sets if future-proofing is necessary. Ensure pin compatibility remains consistent when considering alternative single-channel sensors from other manufacturers.
