AW2027 is a three-channel constant current LED driver with auto charging indication function. The maximum output current is 4-level selectable (5mA/10mA/15mA/30mA). The driving current of each LED has 16 levels configurable so as to achieve 4096 color mixing. The 256-level exponential PWM creates fine and smooth dimming effect even in low brightness. AW2027 can provide auto charging indication under the condition of low battery voltage. When the voltage of battery is too low, and the I2C interface halts, the internal pattern controller will be activated by pulling pin CHRG to high, and pin LED1 will output blinking lighting with period of 2s and max 6mA current. AW2027 contains three independent pattern controllers. Three LEDs can be controlled to work synchronously or individually according to different applications. AW2027 is available in a 1.5mm×1.5mm×0.45mm DFN-8L package.
