Working Principles

MTCH101-I/OT utilizes capacitive touch sensing technology to detect changes in capacitance caused by a user's touch. It employs an internal oscillator to generate an electric field on the touchpad surface. When a conductive object, such as a finger, approaches the touchpad, it causes a change in the capacitance, which is detected by the IC. The touch controller then processes this information and provides the corresponding output.
