Signal line 256 Gray level 3 channal Constant current LED drive IC

More info
Accessories

These 3-channel constant current LED drivers are great for controlling chains of RGB LEDs. The IC is controlled by a 2-wire serial control scheme that allows multiple ICs to be chained together.

Use a handful of these ICs in conjunction with some RGB LEDs to make color displays, or with regular LEDs for a monochrome display three times the size. Or just the WS2811 to free up PWM pins on your microntroller by controlling multiple LEDs with two pins.

Features:

Output port compression 12V.
Built in stabilivolt, Only add a resistance to IC VDD feet when under 24V power supply.
Gray level 256 can be adjusted and scan freque ncy not less than 400Hz/s.
Built in signal reshaping circuit,after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
Built-in electric reset circuit and power lost reset circuit.
Cascading port transmission signal by single line.
Any two point the distance more than 10m transmission signal without any increasecircuit.
When the refresh rate is 30fps, low speedmodelc ascade number are not less than 512 points, high speed mode not less than1024 points.
Send data at speeds of up to 400 Kbps and 800 Kbps two patterns.
