AW9110B is a 10-channel LED controller with I2C
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 I2C interface. The default
IMAX 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 8μs 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.
AW9110B is available in TQFN3X3-20L package.
The operating voltage range is 2.5V~5.5V.
