Overview

The IS31SE5104 is a low power, fully integrated 4-channel solution for capacitive touch button 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 active low interrupt signal is generated on the INTB pin whenever a button event (touched or released) is detected. The triggered and cleared condition can be configured by setting the interrupt register. IS31SE5104 is available in either a QFN-16 (3mm × 3mm) or SOP-16 package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
