MTCH101-I/OT Single-Channel Capacitive Touch Sensor

The MTCH101 provides an easy way to add proximity or capacitive touch detection to any human interface application. The device integrates a single-channel capacitive proximity detection, which can work through plastic, glass or wood-front panel. It also supports a wide range of conductive materials as sensor, like copper pad on PCB, silver or carbon printing on plastic, Indium Tin Oxide (ITO) pad, wire/cable, etc. On-board adjustable sensitivity and Power mode selection allow the user to configure the device at run time easily. An active-low output will communicate the state of the sensor to a host/master MCU, or drive an indication LED.
