WS2814 Datasheet | Worldsemi

feature - The R, G, B, and W output ports can withstand 20V, and the DIN1 and DIN2 ports can withstand 9V. - The chip has a built-in voltage regulator. For power supplies of 24V and below, only a resistor needs to be connected to the IC VDD pin, and no external voltage regulator is required. - Built-in signal shaping circuit. After any pixel receives the signal, it undergoes waveform shaping before outputting it, ensuring that line waveform distortion will not accumulate. - Built-in power-on reset and power-off reset circuits. - The PWM control end can achieve 256-level adjustment, with a scanning frequency of 2KHz. - Serial cascade interface, which can plete data reception and decoding through a signal line. - Breakpoint resume transmission, in the event of a single chip being damaged, does not affect the overall display effect. - No circuit needs to be added when the transmission distance between any two points does not exceed 2 meters. - The color of the light is highly consistent, and the cost-effectiveness is high. - When the refresh rate is 30 frames/second, the number of cascades is not less than 1024 points. - The data transmission speed can reach 800Kbps. Main application areas - LED full-color luminous character light string, LED full-color soft light bar, hard light bar, LED guardrail tube. - LED point light source, LED pixel screen, LED special-shaped screen. Product Overview WS2814 is a four-channel LED drive control dedicated circuit. The chip contains an intelligent digital interface data latch signal shaping and amplification drive circuit, a high-precision internal oscillator, a 20V high-voltage programmable constant current output driver, and a high-precision constant current control module, which effectively ensures that the color of the pixel light on the drive circuit is highly consistent. The data protocol uses a single-line return-to-zero code munication method. After the chip is powered on and reset, the DIN1 end receives the data...
