The Microchip MTCH112 Dual- Channel Proximity/Touch Controller provides an easy way to add proximity and/or touch sensor detection to any application. The device implements either two capacitive sensors or one sensor and one active guard driver, which is improving proximity performance. The optional device configuration through I2C™ allows presets to be loaded in a production environment. Automatic calibration routines are used by default to choose the best options, so user configuration is not required.
