MICROCHIP MTCH1030-E/ST

The Microchip MTCH1030 Capacitive Touch Controller with digital output provides a simple way to add robust water-tolerant touch detection or proximity sensing to any application. This device implements up to three capacitive sensors with Driven Shield+ capability. Sensitivity, measurement period and oversampling can be easily configured via three dedicated pins at run-time, enabling the optimization of power consumption. In addition, MTCH1030 provides Easy Tune-enabling out of the box usage even under changing noise conditions. The MTCH1030 embeds advanced optimization algorithms to actively suppress noise from the signal to achieve reliable touch detection in challenging noise environments. The MTCH1030 provides up to three capacitive touch and proximity detection sensors which can work through plastic, wood or metal front panels with Microchip’s proprietary Metal over Capacitive (MoC) technology. It supports a wide range of conductive materials as sensors, such as copper pads on PCB, silver ink, PEDOT carbon printing on plastic film and Indium Tin Oxide (ITO) pads. Individual open-drain active-low output will communicate the state of each sensor to a host microcontroller or drive an indication LED.
