Worldsemi WS2814
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 communication method.| Part No. | WS2814 |

WS2814 Single-line 256-level grayscale four-channel dual-input constant current LED driver IC Main 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 complete 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.
