GENERAL DESCRIPTION
AW2015/AW2015A is a three channels constant
current LED driver with auto charging indication
function. The max output current is 4-level
selectable among 3mA, 6mA, 12mA and 25mA.
Each LED is 256 current levels configurable so as
to achieve 256*256*256 color mixing. The 256-
level dimming and 12 bits PWM resolution create
fine and smooth dimming effect even in low
brightness.
AW2015/AW2015A can provide auto charging
indication under the condition of low battery
voltage. When the voltage of battery is too low, and
the I
2
C interface can’t work, the internal pattern
controller will be activated if CHRG_F pin is high.
LED1 of AW2015 will output breathing effect with
period of 5s and 6mA max current. LED1 of
AW2015A will hold LED on with 3mA output
current.
In shut down mode, AW2015/AW2015A turn off all
internal circuit and the consumption is less than
1μA. In standby mode, I
2
C interface works and the
consumption is less than 10μA.
The device requires only 2.4V~5.5V single power
supply. An I
2
C compatible interface in 400kHz fast
mode is provided, the device address is 0x64.
AW2015/AW2015A is available in a ultra-thin 8 pin
FCQFN 1.2mm×1.2mm×0.37mm package.
