MTCH1010T-V/SN

Overview

The MTCH1010T-V/SN is a single-channel capacitive touch controller from Microchip Technology, packaged in an 8-lead SOIC (SOIC150). It operates within a supply voltage range of 2V to 5.5V and supports an industrial temperature range of -40°C to +105°C. The device features one capacitive sensor input with active guarding capability and provides an open-drain active-low output for touch indication. Configuration parameters including response time, oversampling, and sensitivity are adjustable via CFG input pins at run time.

Feature Summary

• Capacitive touch sensing with high signal-to-noise ratio
• Water tolerant touch detection through various front panels
• Multi-stage active noise suppression filters
• Automatic environmental compensation and drift correction

Applications

• Light and Internet of Things (IoT) switches
• Power buttons for appliances
• White goods and office equipment interfaces
• Display and keypad back-lighting activation by proximity
• Presence detection systems

Procurement Notes

Verify the ordering code MTCH1010T-V/SN against official Microchip documentation to confirm the specific tape and reel packing media and extended temperature rating. Ensure compatibility with the required operating voltage and interface requirements before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring a single touch channel with hardware-configurable sensitivity and response times. The device eliminates firmware overhead by handling touch detection algorithms internally. Consider the SOIC package constraints and driven shield requirements for optimal performance in noisy environments.

Part Context

The MTCH1010 belongs to the MTCH series of capacitive touch controllers designed for embedded systems. It offers a simple integration path for adding water-tolerant touch or proximity sensing without complex firmware development. The T suffix indicates tape and reel packaging suitable for automated assembly processes.

Replacement Considerations

Direct replacements include other variants within the MTCH1010 family such as MTCH1010-V/SN for tube packaging. Cross-series alternatives like MTCH101 or MTCH1030 offer different channel counts and may require schematic redesigns.
