说明

AW21024E is a 24-channel high precision constant current LED driver. Each channel has individual 8-bit DC current setting for color-mixing and 16-bit PWM current for brightness control. The global current of each channel is recommended to be 50mA configured via register GCCR 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 phase-shifting and spread spectrum technology are utilized to reduce EMI and audible noise caused by MLCC when LEDs turn on in off simultaneously.
AW21024E can be turned off with minimum current consumption by either pulling the EN pin low in using the software shutdown feature.
AW21024E is available in QFN 4mmX4mmX 0.85mm-32L package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
