AW2015/AW2015A 3 Channel LED Drivers with Auto Charging Indication
FEATURES
GENERAL DESCRIPTION
3-channel constant current LED drivers
4-level IMAX selections: 3/6/12/25mA
256 current levels setting for each LED
Supports 256*256*256 color-mixing
256-level PWM dimming, 12-bit PWM resolution
Support charging indication under low battery
voltage condition
Directly start up LED1 via pulling pin
CHRG_F up to high
AW2015: LED1 Breathing period: 5s, Max
AW2015/AW2015A is a three channels constant
current LED driver with auto charging indication
function. The max output current is 4-level
l
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-
a level dimming and 12 bits PWM resolution create
i fine and smooth dimming effect even in low
brightness.
t AW2015/AW2015A can provide auto charging
indication under the condition of low battery
n voltage. When the voltage of battery is too low, and
output current: 6mA
AW2015A: LED1 always on, output
current: 3mA
Automatic breathing light with flexible pattern
configuration and running mode
three independent pattern controllers
pulses repeating, multiple colors alternative
multiple patterns running successively or
cyclically
400kHz fast I2C interface , 1.8V~3.3V
e the I2C interface cant work, the internal pattern
controller will be activated if CHRG_F pin is high.
LED1 of AW2015 will output breathing effect with
fid 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, I2C interface works and the
nconsumption is less than 10μA.
The device requires only 2.4V~5.5V single power
supply. An I2C compatible interface in 400kHz fast
I2C address: 0x64
Single power supply, 2.4V~5.5V
Low power consumption
omode 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.
C Less than 1μA in shut down mode
Less than 10μA in standby mode
