Overview
SX8634 Low Power, Capacitive Button and Slider Touch Controller (12 sensors) with Enhanced LED Drivers and Proximity Sensing ADVANCED COMMUNICATIONS & SENSING DATASHEET GENERAL DESCRIPTION The SX8634 is an ultra low power, fully integrated 12-channel solution for capacitive touch-buttons and slider applications and proximity detection.
Unlike many capacitive touch solutions, the SX8634 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.
The SX8634 includes a capacitive 10 bit ADC analog interface with automatic compensation up to 100pF.
The high resolution capacitive sensing supports a wide variety of touch pad sizes and shapes and allows capacitive buttons to be created using thick overlay materials (up to 5mm) for an extremely robust and ESD immune system design.
