Microchip Technology MTCH6301 Capacitive Touch Controller

Microchip Technology MTCH6301 Projected Capacitive Touch Controller is a turnkey projected capacitive touch controller that allows easy integration of multi-touch and gestures to create a rich user interface in your design. Microchip MTCH6301 uses a sophisticated combination of Self and Mutual Capacitive scanning for both XY screens and touchpads, allowing designers to quickly and easily integrate projected capacitive touch into their application. These controllers are ideal for use in a variety of applications, including Human-machine interfaces with configurable buttons, keypads, or scrolling functions, home automation control panels, and more.
