6-LED Driver and GPIO Controller

AW9106B is a 6-channel LED controller with I 2 C interface. Each channel can be used for GPIO. LED dimming combined with extended GPIO function, which can give full play to the application value of single chip. AW9106B configures the current level to realize 256 steps linear dimming with I 2 C interface. The default  I MAX current is 37mA. When OUTx works in a GPIO input mode, AW9106B detected input state to occur interrupt with internal  8 μ s  debounce. AW9106B supports two intelligent breathing modes: BLINK mode and SMART-FADE mode. BLINK mode allows LED automatic to flash periodically according the setting time parameter. AW9106B is available in QFN3mmX3mm-20L package. The operating voltage range is 2.5V~5.5V.
