WS2818 Overview
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 constant current control part, which achieves highly consistent color effect.
WS2818 Key Features
- 12V/24V available, that work on different
WS2818 Applications
- 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
- 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
