20 Programmable LED Driver
AW9120
Feb. 2019 V1.4
FEATURES
8-level LED Maximum Current for each LED,
GENERAL DESCRIPTION
AW9120 integrates a SRAM program-controlled 20
l
max 24.5mA
Internal ASP with 256×16bit SRAM
Programmable to Achieve Custom Light Effect
256-level Linear/Logarithmic PWM Dimming,9
bits PWM resolution
tia LED driver. 20 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 I2C Interface, VIO: 1.8V ~ 3.3V
I2C address: 0x2C/0x2D
Single Power Supply, Voltage Range: 3.0V ~
4.5V
QFN 4mm×4mm×0.75mm-28L Package
Compatible I2C interface of 400kHz fast mode is
n provided. It requires only 3.0V-4.5V single power
e supply.
