AW9110BTQR

10-LED Driver and GPIO Controller

AW9110B is a 10-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. AW9110B configures the current level to realize 256 steps linear dimming with I 2 C interface. The default I MAX current is 37mA. AW9110B strengthens the dropout performance of low 6 channel LED driver and only 60mV current source voltage drop can provide 20mA LED current that can make it more suitable for the driver of LCD backlight. When OUTx(x=0~9) works in a GPIO input mode, AW9110B detected input state to occur interrupt with internal  8 μ s  debounce. AW9110B supports two intelligent breathing modes: BLINK mode and SMART-FADE mode. BLINK mode allows LED automatic to flash periodically according the setting time parameter. OUT0~OUT5 support intelligent breathing mode.
