MTCH6102-I/MV

Overview

The MTCH6102-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 operating temperature range of -40°C to +85°C. Communication is handled via an I²C interface supporting speeds up to 400 kbps. Key electrical characteristics include standby current below 500 nA and active mode current under 12 µA. It provides 12-bit resolution coordinate reporting and configurable frame rates exceeding 200 reports per second.

Procurement Notes

Verify the ordering suffix 'MV' corresponds to the 28-pin UQFN package type when sourcing. Confirm the '-I' suffix indicates the industrial temperature range (-40°C to +85°C). Ensure compatibility with the host system's I²C voltage levels within the 1.8V to 3.6V operating range. Check for any specific revision notes in the latest datasheet DS40001750A regarding pinout or electrical characteristics.

Selection Notes

Select this component for applications requiring single-finger gesture recognition with minimal power budget. It is suitable for designs using PCB, film, glass, or FPC sensors with cover layers up to 3mm plastic or 5mm glass. Ensure the host microcontroller supports I²C communication and can process the reported coordinate data. Consider the 28-pin UQFN footprint constraints during PCB layout.
