WS2818B
Single-line 256 Gray-level 3-channel Constant Current LED Driver IC
Features
12V application. Built-in VR-tube, only add a resistance to IC VDD-pin if under 12V, no external VR-tube needed. Adopts the built-in signal reshaping circuit to achieve the signal waveform shaping, and thus no signal waveform
distortion takes place. Built-in power-on reset and brown-out reset circuits. The gray levels of each pixel of 256 levels, and the refresh frequency reaches to 2KHz. Serial cascading interface, data receiving and decoding are all achieved by one signal line. Signal Break-point Continuous Transmission, any pixel’s failure, it won’t affect the whole display effect. The distance of any two signal transmission points is less than 5 meters, there’s no extra circuits needed.
