描述 Description

9 Programmable LED DriverAW9109 integrates a SRAM program-controlled 9LED driver. 9 LED driver uses common anodecurrent source and PWM dimming. Each LED is8-level driver current selectable with dimmingindependently controlled by external MCU orinternal 256word*16bit SRAM program.Compatible I 2 C interface of 400kHz fast mode isprovided, the package is QFN 3mm×3mm -20L. Itrequires only 3.0V-4.5V single power supply.
