WorldSemi WS2818
WS2818 is a 3-channel LED driver control circuit, its internal include intelligent digital port data latch and signal reshaping amplification drive circuit. The user can select the first chip DIN/BIN as the control signal input pin, and the follow-up cascade chips will automatically identify the output signal released by the first chip which not to affect the whole display effect. WS2818 has strong features in Signal Break-point Continuous Transmission, it adopts dual signal transmission, these signals are able to work together without interaction.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.
