AW9109QNR

9 Programmable LED Driver

AW9109 integrates a SRAM program-controlled 9 LED driver. 9 LED driver uses common anode current source and PWM dimming. Each LED is 8-level driver current selectable with dimming independently controlled by external MCU or internal 256word*16bit SRAM program. Compatible I 2 C interface of 400kHz fast mode is provided, the package is QFN 3mm×3mm -20L. It requires only 3.0V-4.5V single power supply.
