MTCH1010 Datasheet | Microchip Technology

Description The Microchip MTCH1010 Touch Controller with digital output provides a simple way to add water tolerant touch detection or proximity sensing to any application. This device implements one capacitive sensor with active guarding capability. Sensitivity, response time, and oversampling can be configured via CFG input pins at run time. The MTCH1010 uses advanced optimization algorithms to actively suppress noise from the signal to achieve reliable touch detection. The MTCH1010 provides one capacitive touch/proximity detection sensor which can work through plastic, wood, or even metal front panels with Microchip’s proprietary Metal Over Capacitive (MOC) technology. It also supports a wide range of conductive materials as sensors, such as copper pad on PCB, silver ink, PEDOT or carbon printing on plastic film, Indium Tin Oxide (ITO) pad, wire/cable, etc. An open-drain active-low output will municate the state of the sensor to a host microcontroller or drive an indication LED.
