MTCH1060-I/SS

Overview

The MTCH1060-I/SS is a six-channel capacitive touch controller from Microchip Technology, housed in a 20-pin SSOP package. It supports up to six sensors with Driven Shield+ capability and Metal over Capacitive (MoC) technology for detection through conductive materials. The device operates within a voltage range of 2V to 5V and functions across temperatures of -40°C to +85°C. Configuration of measurement period, oversampling, and sensitivity is managed via dedicated pins, allowing runtime optimization of power consumption and response time.

Feature Summary

• Implements up to six capacitive sensors with Driven Shield+ capability for robust water-tolerant touch detection.
• Features Easy Tune functionality for automatic sensitivity adjustment under changing noise conditions without external components.
• Supports Metal over Capacitive (MoC) technology to detect touch through plastic, wood, or metal front panels.
• Provides individual open-drain active-low outputs for direct communication with host microcontrollers.

Applications

• Consumer electronics requiring water-resistant touch interfaces
• Industrial control panels with metal overlays
• Appliances needing low-power standby modes via single-button wake-up
• Medical devices requiring reliable touch sensing through sealed enclosures

Procurement Notes

Verify the suffix 'I' indicates industrial temperature rating (-40°C to +85°C). Confirm the '/SS' denotes the 20-pin SSOP package. Ensure compatibility with host logic levels if operating near voltage boundaries. Check for recent datasheet revisions affecting configuration pin behaviors.

Selection Notes

Select this component when six independent channels are required with minimal external tuning complexity. Ideal for applications where environmental noise varies significantly, leveraging the Auto-Tune feature. Consider if the SSOP package fits the PCB layout constraints compared to VQFN alternatives. Evaluate power budget against the configurable measurement periods.

Part Context

This part belongs to Microchip's MTCH106x family of capacitive touch controllers. It shares core architecture with other variants but differs in package type and temperature grade. The I/SS designation specifically identifies the industrial-grade version in the small-outline package, distinguishing it from commercial grades or quad-flat no-lead options.

Replacement Considerations

Check for MTCH1060-V/SS for commercial temperature range equivalents. Verify functional compatibility with MTCH1061 if fewer channels suffice. Ensure pinout alignment when substituting with older MTCH10xx series parts, noting potential differences in drive strength or configuration logic.
