概觀

The IS31SE5100 is an ultra low power, fully integrated 8-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 IS31SE5100 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 configured by setting the interrupt register. IS31SE5100 is available in QFN-24 (4mm × 4mm) and SSOP-24 packages. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
