描述 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 I2C 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, I2C interface works and the consumption is less than 10μA.
The device requires only 2.4V~5.5V single power supply. An I2C 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.
