IQS128-00000-TSR

Overview

The IQS128-00000-TSR is a single-channel capacitive touch and proximity sensor controller from Azoteq, part of the ProxFusion product line. It integrates sensing capabilities for button detection and proximity monitoring within a compact TSOT-23-6 package measuring 3 mm x 1.7 mm x 1 mm. The device operates on a digital interface with active high/low signaling and functions across a supply voltage range of 2.5 V to 5.5 V. It supports an industrial temperature range from -40°C to +85°C. The component is supplied in tape and reel packaging, facilitating automated surface-mount assembly.

Feature Summary

• Integrates single-channel capacitive touch and proximity sensing functions
• Features intelligent hysteresis for stable signal processing
• Supports direct digital output interfaces

Applications

• Consumer electronics requiring compact touch controls
• Industrial equipment with proximity monitoring needs
• Automotive interior sensors

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and configuration. Check current availability status as distribution channels may vary. Ensure compatibility with existing PCB footprints and voltage levels before integration. Confirm RoHS compliance documentation is available for regulatory requirements.

Selection Notes

Select this component for applications requiring a minimal footprint for single-point touch or proximity detection. Consider the TSOT-23-6 package size constraints and the 2.5V to 5.5V operating voltage range. Evaluate if the single-channel capability meets system requirements compared to multi-channel alternatives.

Part Context

This part belongs to Azoteq's ProxFusion series, which combines multiple sensor technologies on a single chip. The IQS128 specifically focuses on capacitive sensing solutions. It represents the company's expertise in low-power, high-reliability sensor controllers developed since its founding in 1998.

Replacement Considerations

Check for end-of-life notices. Verify functional equivalents within the same IQS family or other single-channel capacitive controllers with compatible packages and voltages.
