3-Channel LED Drivers with I2C Interface
FEATURES
GENERAL DESCRIPTION
l
3-channel constant current LED drivers
4-level global maximum current: 5mA, 10mA,
15mA, 30mA
16-level individual current, 4096 mixed-color
available
tia AW2023 is a three channels constant current LED
driver. The max output current is 4-level selectable
(5mA/10mA/15mA/30mA). Each LED is 16 current
levels configurable so as to achieve 4096 color
mixing. The 256-level exponential PWM dimming
256-level individual PWM dimming
Automatic breathing lighting
Three individual pattern controllers
Individual and sync control selectable
LED current accuracy: ±3%
LED matching accuracy: ±3%
Low dropout voltage: 50mV
Low power consumption
ISTB<5uA in standby mode
UVLO and OT protection
n creates fine and smooth dimming effect even in low
brightness.
AW2023 contains three independent pattern
controllers. All LEDs can be controlled to work
e synchronously or individually due to the practical
application.
