AW2033 is a three channels constant current LED driver with multi-mode auto charging indication function. The global 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.
AW2033 provides multi-mode 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 wanted lighting can be output on pin LED0 by triggering pin CHRG. The pin SET1/SET2 select the lighting effect and the active trigger level of pin CHRG respectively.
AW2033 contains three independent pattern controllers. Three LEDs can be controlled to work synchronously or individually according to different applications.
A 400kHz I2C interface is provided with 1.8V~3.3V interface voltage. The tiny 2mm×2mm DFN-10L package occupies very small PCB area.
