Capacitive Sensor Switch Control ICs - BU21072MUV

BU21072MUV/BU21078MUV is a capacitive sensorcontroller for switch operation.
In addition to a regular simple switch, support matrixswitches which are arranged in the matrix sensors. Ifexternal noise and temperature drift are detected, theautomatic self-calibration is operated.
Include LED controller with PWM function.
