IS31SE5118A - Lumissil

IS31SE5118A 8-CH PROGRAMMABLE CAPACITIVE TOUCH SENSOR

IS31SE5118A is an ultra-low power, 8-channel capacitive touch controller. The controller allows sleep mode and uses auto-detection for wakeup. It also provides a shield output to increase moisture immunity. The built-in hardware monitor and calibration for the environment feature is to prevent false triggers. A host MCU is required to communicate with IS31.
