Frequently Asked Questions
How many touch input channels does the MTCH108-I/GZ support, and can they operate simultaneously?
The MTCH108-I/GZ supports 8 independent projected capacitive touch input channels. Each of the 8 channels can be individually configured and monitored for touch events, and the device processes all channels sequentially in its internal scan cycle. This allows touch detection across up to 8 sensor pads or electrodes without requiring an external microcontroller for signal processing.
What package does MTCH108-I/GZ use and how does it affect PCB layout for a touch panel design?
The MTCH108-I/GZ is housed in a UQFN-20 ultra-thin quad flat no-lead package with 20 pins and matte tin (Sn) terminal finish. The compact no-lead footprint enables placement very close to capacitive sense electrodes, minimizing parasitic trace capacitance on the 8 sense channels. This proximity is important for maintaining sensitivity, as each additional millimeter of trace length between the IC and sensor pad adds parasitic capacitance that degrades touch detection thresholds.
When is MTCH108-I/GZ preferable to a microcontroller-based capacitive touch solution for an appliance control panel?
MTCH108-I/GZ is preferable when the application needs 8 or fewer touch buttons and the system cannot afford the BOM cost or firmware complexity of a dedicated MCU. Because MTCH108-I/GZ integrates all signal conditioning and auto-calibration internally, design teams save weeks of touch firmware development. For appliances such as dishwashers or cooktops with up to 8 fixed control buttons operating from 1.8 V to 3.3 V supply rails, the MTCH108-I/GZ provides a complete single-chip touch detection solution.
