MTCH6102T-I/MV

Overview

The MTCH6102T-I/MV is a low-power projected capacitive touch controller manufactured by Microchip Technology, housed in a 28-pin UQFN package. It supports up to 15 sensor channels for gesture detection including taps, swipes, and scrolling. The device operates on a 1.8V to 3.6V supply with an active current consumption of less than 12 µA and standby current below 500 nA. Communication is handled via an I²C interface supporting speeds up to 400 kbps. It provides 12-bit resolution coordinate reporting and configurable frame rates exceeding 200 reports per second.

Feature Summary

• Supports up to 15 RX channels for XY touch pads and screens
• I²C interface with interrupt and sync signal outputs
• Active mode current <12 µA; Standby mode <500 nA
• Gesture detection for taps, swipes, and scrolling

Applications

• Wearable devices such as headphones, watches, and fitness wristbands
• Track pads and computer peripherals
• Input devices with configurable buttons or scrolling functions
• Home automation control panels and security keypads
• Automotive center stack controls and gaming devices

Procurement Notes

Verify the ordering suffix 'MV' corresponds to the 28-pin UQFN package and tape-and-reel packaging configuration. Confirm the '-I' suffix indicates the industrial temperature range of -40°C to +85°C. Ensure compatibility with the host system's I²C voltage levels within the 1.8V to 3.6V operating range.

Selection Notes

Select this component for applications requiring low power consumption and gesture support. Ensure the design accommodates up to 15 sensor channels and allows for cover layers up to 5 mm of glass or 3 mm of plastic. Verify that the PCB layout supports the 28-pin UQFN footprint and includes necessary decoupling capacitors close to the VDD and VSS pins.

Part Context

The MTCH6102 series simplifies integration of projected capacitive touch interfaces. The 'T' in the part number typically denotes reel packaging, while 'MV' specifies the UQFN package type. This controller is designed for cost-sensitive, size-constrained applications where power efficiency is critical.
