IS31SE5120A 24-CH PROGRAMMABLE CAPACITIVE TOUCH SENSOR

IS31SE5120A is an ultra-low-power, 24-channel capacitive touch controller. The controller allows sleep mode (under 10uA) and uses auto-detection for wakeup. It also provides a shield output to increase moisture immunity. The built-in hardware monitor and calibration feature for the environment is to prevent false triggers. A host MCU is required to communi.
