The SX8636 is an ultra low power, fully integrated 8-channel solution for capacitive touch-buttons and proximity detection applications. Unlike many capacitive touch solutions, the SX8636 features dedicated capacitive sense inputs (that requires no external components) in addition to 8 general purpose I/O ports (GPIO). Each GPIO is typically configured as LED driver with independent PWM source for enhanced lighting control such as intensity and fading.
