MTCH1060T-E/SS

Overview

The MTCH1060T-E/SS is a six-channel capacitive touch controller from Microchip Technology, housed in a 20-pin SSOP package. It provides robust water-tolerant touch detection and proximity sensing using Driven Shield+ technology and Metal over Capacitive (MoC) support. The device features six individual open-drain active-low outputs for sensor state indication. Key electrical specifications include an operating voltage range of 2V to 5V and an industrial temperature range of -40°C to +85°C. Configuration parameters such as measurement period, oversampling, and sensitivity are adjustable via dedicated pins.

Feature Summary

• Implements up to six capacitive sensors with Driven Shield+ capability for enhanced noise suppression.
• Supports touch detection through plastic, wood, or metal front panels using proprietary Metal over Capacitive technology.
• Features Easy Tune functionality for automatic sensitivity adjustment under changing noise conditions.
• Includes Single-Button mode to reduce power consumption by scanning only one sensor.

Applications

• Consumer electronics requiring water-resistant touch interfaces
• Industrial control panels with metal overlays
• Appliances needing robust proximity sensing
• Medical devices with sealed touch surfaces

Procurement Notes

Verify the complete part number including the suffix 'T-E/SS' to ensure correct packaging and temperature grade. Confirm that the SSOP package variant matches your PCB footprint requirements. Check for any specific revision history updates in the latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a fixed six-channel solution with hardware-based tuning is required. Ensure the application supports the 2V to 5V supply range. Consider the SSOP package constraints if board space is limited. Verify that the host microcontroller can interface with the open-drain outputs or drive LEDs directly.

Part Context

This part belongs to the MTCH1060 family of capacitive touch controllers. The 'T' indicates tape and reel packaging, while 'E' denotes the extended industrial temperature range. The '/SS' specifies the 20-pin Shrink Small Outline Package. It serves as a standalone alternative to MCU-integrated touch solutions for simpler applications.

Replacement Considerations

Direct substitutes within the same family include other MTCH1060 variants with different packages or temperature grades. Cross-family replacements may require significant schematic and firmware changes due to differing pinouts and configuration methods. Verify compatibility with existing sensor layouts before substitution.

FAQ

How is the sensitivity adjusted on the MTCH1060?

Sensitivity is configured via the CFG2 pin. A voltage applied to this pin determines the sensitivity level, with lower voltages providing lower sensitivity and higher voltages increasing it. If Easy Tune is enabled, sensitivity is automatically managed based on noise levels.

Can the MTCH1060 detect touch through metal covers?

Yes, the MTCH1060 supports Metal over Capacitive (MoC) technology, allowing it to detect touch through plastic, wood, or metal front panels without requiring direct contact with the sensor electrode.

What is the function of the Single-Button mode?

Single-Button mode reduces power consumption by scanning only Button0. It is typically used for power-on keys. After activation, if no touch occurs for five seconds, the device enters a low-power state where only Button0 is monitored until touched again.
