Description

AW21024 is a 24-channel high precision constant current LED driver. Each channel has individual 8-bit DC current setting for color-mixing and 8-bit PWM current for brightness control. The maximum global current of each channel is recommended to be 50mA configured via internal 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. AW21024 can be turned off with minimum current consumption by pulling the EN pin low. AW21024 operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
