MTCH1060-E/SS

Overview

The MTCH1060-E/SS is a six-channel capacitive touch controller manufactured by Microchip Technology, housed in a 20-pin SSOP package. It operates within a supply voltage range of 2 V to 5.5 V and supports an industrial temperature range from -40°C to +125°C. The device features up to six capacitive sensors with Driven Shield+ capability and provides individual open-drain active-low outputs for each channel. Configuration parameters including measurement period, oversampling, and sensitivity are adjustable via dedicated CFG pins or the Easy Tune feature.

Feature Summary

• Implements up to six capacitive sensors with Driven Shield+ technology for enhanced signal-to-noise ratio
• Provides water-tolerant touch detection and proximity sensing through plastic, wood, or metal front panels using Metal over Capacitive (MoC) technology
• Features Easy Tune capability for automatic run-time sensitivity adjustment based on observed noise levels
• Supports flexible configuration of measurement period, oversampling, and sensitivity via dedicated input pins

Applications

• Water-resistant control panels for kitchen appliances and outdoor equipment
• Proximity sensing and gesture detection interfaces
• Replacing mechanical switches in consumer electronics and IoT devices
• Industrial control systems requiring robust environmental compensation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with host microcontroller logic levels for the open-drain outputs. Confirm that the selected variant meets the required operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a multi-button interface requires high noise immunity and water tolerance without complex firmware. Evaluate the need for Driven Shield+ functionality if operating in electrically noisy environments. Consider the Single-Button mode feature if power conservation is critical during standby states. Verify that the SSOP package fits the available PCB footprint constraints.

Part Context

The MTCH1060 belongs to the Microchip MTCH series of capacitive touch controllers designed for embedded applications. This series includes variants with varying channel counts and interface options, such as the MTCH1010 single-key and MTCH1030 three-key controllers. The MTCH1060 specifically targets applications requiring up to six independent touch inputs with hardware-configurable tuning capabilities.

Replacement Considerations

Direct substitutes within the same family include the MTCH1060T-E/SS, which shares identical electrical characteristics but differs in tape-and-reel packaging. Cross-family replacements like the MTCH1030 offer fewer channels and may not support the full six-input requirement.
