1.Product description:   

    LC8812B Side 4020 is an intelligent externally controlled LED that integrates a control circuit and a light-emitting circuit. Its appearance is the same as a 4020 LED . Each LED is a pixel. The LED contains an intelligent digital interface data latch signal circuit. , Power supply voltage regulator circuit, built-in constant current circuit, data regeneration circuit, high precision RC oscillator, output drive adopts patented PWM technology, which effectively guarantees the color consistency of the each pixel.

    The data protocol adopts a unipolar return-to-zero code communication method. After the LED is powered on, the DIN terminal receives external signal data, and the data regeneration circuit automatically reshapes and forwards the cascaded output data to ensure that the data is transmitted in series without attenuation and normal transmission .

    LC8812B-4020 has the advantages of low voltage drive, environmental protection and energy saving, high brightness, large scattering angle, good consistency, long life and so on. The control circuit is integrated inside the LED, which makes the application circuit design easier, less original parts, and small in size. Beautiful, easier to install.

3.Feature：   

    ■ Smart SMD integrates high-quality external control single-wire serial cascaded constant current IC.

    ■ The control circuit  and chip are integrated in SMD components to form a complete externally controlled pixel point, 

       color, color temperature,  uniform effect and high consistency,and the default output constant  Current Value,OUTR/

      OUTG/OUTB is 12MA

    ■ Built-in data shaping circuit, any pixel point receives the signal after waveform shaping and then output to ensure

that the signal waveform distortion will not accumulate. Data shaping: After receiving the data of this unit, the

subsequent data will be shaped and output automatically.

    ■ Built-in power-on reset and power-down reset circuits, the light does not light up after power-on.

    ■ Single-wire data transmission, unlimited cascading, data sending rate 800Kbps synchronous refresh

    ■ Grayscale adjustment circuit (256-level grayscale is adjustable).

    ■ Vertical SMD surface mount package, suitable for all SMT assembly and soldering processes.

    ■ Moisture-proof grade: LEVEL5a.

    ■ CE, RoHS certification.
