Applications
The MTCH102-I/MS is used in consumer electronics, home appliances, and industrial control panels where simple 2-button capacitive touch input is needed without the overhead of a microcontroller-based touch library. Its direct GPIO output makes it easy to integrate into existing logic circuits, replacing mechanical push buttons with touch pads behind glass or plastic overlays up to 3 mm thick. The device is also suited for wearable devices and IoT accessories where a tactile-free sealed enclosure and ultra-low active current are design priorities.

Frequently Asked Questions
Can the MTCH102-I/MS detect touch through a glass or plastic overlay, and how thick can the overlay be?
Yes, the MTCH102-I/MS is designed to detect capacitive touch through non-conductive overlays such as glass or plastic. It reliably senses a finger through overlays up to approximately 3 mm thick, depending on electrode pad area, which is sufficient for most consumer electronics front panels, appliance control surfaces, and industrial touch button covers.
How does the MTCH102-I/MS simplify integration compared to a full capacitive touch controller with I2C or SPI interface?
The MTCH102-I/MS provides a dedicated active-high logic output per channel at 3.3 V, driven directly by its internal autonomous sensing engine with no firmware or configuration protocol required. Unlike I2C or SPI touch controllers that require register setup, interrupt handling, and calibration code in the host MCU, the MTCH102 connects directly to 2 GPIO input pins, reducing software development effort to zero and saving at least 500 bytes of Flash in the host microcontroller.
For a battery-powered remote control with 2 touch buttons, what is the MTCH102-I/MS's power impact over a 1-year runtime?
The MTCH102-I/MS draws approximately 30 µA average operating current at 3.3 V during continuous touch sensing. Over one year of continuous operation, this equates to roughly 263 mAh of total charge consumption from the battery. For a 1000 mAh lithium polymer cell, the touch controller alone consumes under 27% of battery capacity annually, leaving the majority of the energy budget for the radio, display, and MCU subsystems in a typical 2-button remote control design.
