AW2015 3 Channel LED Drivers with Auto Charging Indication

AW2015 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 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 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 64h. AW2015 is available in a ultra-thin 8 pin FC-QFN 1.2mm×1.2mm×0.37mm package.
