WS2811 ADDRESSABLE RGB LED DRIVER IC

The WS2811 is 3 output channels special for LED driver circuit. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current output drive. In the purpose of reduce power supply ripple, the 3 output channels designed to delay turn-on function.

• • Output port compression 12V.
  • Built in stabilivolt, Only add a resistance to IC VDD feet when under 24V power supply.
  • Gray level 256 can be adjusted and scan frequency not less than 400Hz/s.
  • Built in signal reshaping circuit,after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
  • Built-in electric reset circuit and power lost reset circuit.
  • Cascading port transmission signal by single line.
  • Any two point the distance more than 10m transmission signal without any increase circuit.
  • When the refresh rate is 30fps, low speed model cascade number are not less than 512 points, high speed mode not less than1024 points.
  • Send data at speeds of up to 400 Kbps and 800 Kbps two patterns.
