4-CH CAPACITIVE TOUCH SENSOR WITH AUTO CALIBRATION December 2013 GENERAL DESCRIPTION The IS31SE5104 is an ultra low power, fully integrated 4-channel solution for capacitive touch-buttons applications. The chip allows electrodes to project sense fields through any dielectric such as glass or plastic. On-chip calibration logic continuously monitors the environment and automatically adjusts on-and-off threshold levels to prevent false sensor activation. The IS31SE5104 supports the 400kHz I²C serial bus data protocol and includes a field programmable slave address. An INTB is generated when a button event (touched or released) occurs, triggered and cleared condition could be...
