6-LED Driver and GPIO Controller
6-channel LED constant-current driver, each
channel can be used for GPIO
OUTx support 2 intelligent breathing mode:
BLINK and SMART-FADE, breathing time is
Support 256 steps linearity dimming, IMAX is
Support GPIO input/output mode
GPIO input mode, internal 8μs debounce
Standard I2C interface
I2C interface and GPIO can operate at 1.8V
Support shutdown function, low level effective
Simple Voltage Range VCC: 2.5V~5.5V
TQFN 3mmX3mmX0.75mm-20L Package
AW9106B is a 6-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
AW9106B configures the current level to realize
256 steps linear dimming with I2C interface. The
default IMAX current is 37mA.
When OUTx works in a GPIO input mode,
AW9106B detected input state to occur interrupt
with internal 8μs 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 TQFN3X3-20L package.
The operating voltage range is 2.5V~5.5V.
