MTCH1010-V/SN

Overview

The MTCH1010-V/SN is a single-channel capacitive touch controller from Microchip Technology, packaged in an 8-pin 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. Sensitivity, response time, and oversampling are configurable via three dedicated CFG input pins at run time. It provides an open-drain active-low output for touch indication.

Feature Summary

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

Applications

• Light and Internet of Things (IoT) switches
• Power buttons
• White goods and appliance controls
• Office equipment interfaces
• Toys and display backlighting activation

Procurement Notes

Verify the specific ordering suffix '-V/SN' against official Microchip documentation to confirm the tube packing media and exact temperature grade. Ensure that the selected package type matches the PCB footprint requirements. Confirm compliance with RoHS directives as indicated in the datasheet. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a single-channel solution with hardware-configurable parameters is required. The MTCH1010 allows adjustment of sensitivity, response time, and oversampling via external voltage levels on CFG pins. Consider the operating voltage range and temperature specifications to ensure compatibility with the target application environment and power supply constraints.

Part Context

The MTCH1010 belongs to the MTCH10xx series of touch controllers designed for embedded systems. This series includes models like the MTCH1030 and MTCH1060, which offer multiple channels. The MTCH1010 specifically focuses on single-channel applications, providing a cost-effective and simple interface for adding water-tolerant touch capabilities without complex firmware overhead.

Replacement Considerations

The MTCH1010T-V/SN is the tape and reel version of the same device. Other single-channel options within the MTCH10xx family may require pinout or configuration adjustments.
