AW2023 is a three channels constant current LED driver. The max output current is 4-level selectable (5mA/10mA/15mA/30mA). Each LED is 16 current levels configurable so as to achieve 4096 color mixing. The 256-level exponential PWM dimming creates fine and smooth dimming effect even in low brightness.
AW2023 contains three independent pattern controllers. All LEDs can be controlled to work synchronously or individually due to the practical application.
An I2C compatible interface in 400kHz fast mode is provided, the device address is 0x45, and continuously writing and reading the internal registers is supported.
AW2023 requires single power supply of 2.5V~5.5V.
