3-Channel LED Drivers with Auto Charging Indicator

AW2016/AW2016A is a three channels constant current LED driver with auto charging indication function. The max output current is 4-level selectable (5mA/10mA/15mA/30mA). The driving current of each LED is 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. AW2016 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 halts, the internal pattern controller will be activated by pin CHRG being pulled high, and pin LED1 of AW2016 will output breathing lighting with period of 4.5s and max 6mA current. LED1 of AW2016A will be always on with 3mA constant current. AW2016/AW2016A contain three independent pattern controllers. Three LEDs can be controlled to work synchronously or individually according to different applications.
