MTCH1060T-I/SS

Overview

The MTCH1060T-I/SS is a six-channel capacitive touch controller manufactured by Microchip Technology, designed for robust water-tolerant touch detection and proximity sensing. It features Driven Shield+ capability and supports Metal over Capacitive (MoC) technology to detect touch through plastic, wood, or metal front panels. The device operates on a supply voltage range of 2 V to 5.5 V and functions within an industrial temperature range of -40°C to +85°C. Configuration of measurement period, oversampling, and sensitivity is managed via dedicated CFG pins. It provides open-drain active-low outputs for each sensor channel.

Feature Summary

• Six capacitive touch channels with Driven Shield+ technology for enhanced signal-to-noise ratio
• Easy Tune feature enabling automatic sensitivity adjustment at run-time based on noise levels
• Supports Metal over Capacitive (MoC) technology for operation through conductive front panels
• Multi-stage active noise suppression filters for reliable performance in challenging environments

Applications

• Water-tolerant touch interfaces for kitchen appliances and outdoor equipment
• Proximity sensing applications requiring detection through non-transparent covers
• Industrial control panels operating in high electrical noise environments
• Embedded systems utilizing GPIO-based touch input without firmware overhead

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with host microcontroller logic levels for the open-drain outputs. Confirm that the SSOP-20 package dimensions align with the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a low-firmware solution with multiple touch inputs is required. The MTCH1060 is suitable for applications needing configurable response times and power consumption trade-offs via hardware pins. Consider the Easy Tune feature if minimizing external tuning components and development time are priorities.

Part Context

The MTCH1060 belongs to the Microchip MTCH series of capacitive touch controllers. This family includes single, three, and twelve-channel variants, offering scalable solutions for embedded systems. The MTCH1060 specifically targets applications requiring up to six channels with flexible GPIO configuration and high noise immunity.

Replacement Considerations

Microchip MTCH1030: Three-channel variant with similar GPIO configuration but fewer sensors. Microchip MTCH1010: Single-channel alternative for simpler applications. Verify pinout compatibility and software interface requirements when substituting.
