AW21012 is a 12-channel multi-function LED driver. Each channel has individual 8-bit DC current setting for color-mixing ａｎｄ maximum 12-bit PWM resolution for brightness control. The global current of each channel is recommended to be 40mA configured via register ａｎｄ external Resistor REXT. Group control mode, autonomous breathing pattern ａｎｄ rapid RGB control mode are provided for flexible, high efficiency lighting effect programming ａｎｄ fast display updating. Programmable spread spectrum technology are utilized to reduce EMI ａｎｄ audible noise caused by MLCC when LEDs turn on ｏｒ off simultaneously. AW21012 can be turned off with minimum current consumption by either pulling the EN pin low ｏｒ using the software shutdown feature. AW21012 is available ｉｎ QFN 3mmX3mmX 0.75mm-20L package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
