Description
The WS2813B/2021 is a smart RGB LED in a compact 2021 SMD package, integrating control logic and RGB LEDs into a single component. It forms a fully addressable pixel and was specifically developed for applications requiring high reliability and fail-safety.
Thanks to the dual data line (DIN / BIN), data transmission remains intact even if a single LED within the chain fails. In combination with an integrated constant current driver, signal amplification, and reset circuit, the WS2813B/2021 ensures uniform brightness, stable color reproduction, and reliable operation even in large LED installations.
Features:
- Integrated control and RGB chip in 2021 SMD package
- Fully addressable RGB pixel
- Dual data line (signal redundancy for uninterrupted operation)
- Built-in signal amplification and reset circuit
- Constant current driver for uniform brightness and color consistency
- No external components required
- Serial data transmission over one line with backup signal
- High refresh rate for flicker-free display
- Low quiescent current and energy-efficient operation
- Good EMC/EMI properties and long lifespan
