WS2818

WS2818 Single-line 256 Gray-level 3-channal Constant Current LED Driver IC Features  12V/24V available, that work on different applications of stable pressure.  Built-in voltage regulator tube, only add a resistance to IC VDD pin when the voltage is below DC24V.  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/s.  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.  When the refresh rate of 30fps, the cascade number are not less than 1024 pixels.  Send data at speeds of 800Kbps.  Good consistency reliability, high cost-effective. Applications  Guardrail tube series, point light display series, flexible/rigid strips series, module series applications.  Lighting stage costumes, innovative gadgets or any other electronic products. General description WS2818 is a 3-channel LED driver control circuit, its internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable consta...
