Overview

The SK6803-T52491H4RGBP6-VC-E-A-002 is a highly integrated, top-face luminescent SMD (Surface-Mount Device) RGB LED produced by Shenzhen Normand Electronic Co., Ltd. This advanced component combines high-quality RGB chips with an integrated control IC (the 68-series SK6803) into a single, compact 6-pin package. Designed for a 24V operating environment, it provides a streamlined and efficient solution for dynamic lighting and consumer electronics.

Key Features

· Operating Voltage & Current: 24V @ 2.1mA (OUT GRB). The logic supply voltage range is 20V to 24V.

· Communication Protocol: Utilizes a single-line zero-code transmission protocol, allowing for infinite cascading of units.

· Data Transmission: Supports a data transmission frequency of up to 800 Kbps. When operating at a refresh rate of 30 frames per second, the cascade number can be less than 1024 points.

· Grayscale Control: Offers 256 levels of grayscale adjustment for smooth color transitions.

· Viewing Angle: 120° typical viewing angle with a translucent epoxy lens.

· Built-in Reset: An integrated reset circuit ensures the LED does not light up unexpectedly upon power-up.

· ESD Protection: 2KV ESD withstand voltage (Human Body Mode).

Applications

This versatile LED component is primarily targeted at the consumer electronics market, where compact size, reliable data transmission, and vibrant color output are required.

Mechanical and Pin Configuration

The device features a compact footprint with dimensions of 5.2 x 4.9 x 1.4 mm (Length x Width x Height). It utilizes a 6-pin (P6) configuration:

· Pin 1 & 6: GND (Ground)

· Pin 2: DIN (Data Input)

· Pin 3 & 4: VIN (Power Supply, 24V)

· Pin 5: DOUT (Data Output)

This pinout facilitates straightforward cascading, where the DOUT of one LED connects directly to the DIN of the next, forming a continuous data chain.

Electrical and Optical Characteristics

Electrical Parameters (Ta=25℃)

· Output Drive Current: 2.1mA typical (VDS=1V).

· PWM Frequency: 4.6 KHz typical.

· Static Power Consumption: 0.5mA to 2.0mA (VIN=24V, outputs off).

· Operating Temperature: -40℃ to +80℃.

· Storage Temperature: -40℃ to +80℃.

Optical Parameters

The LED delivers bright and consistent illumination across the RGB spectrum:

· Red: Wavelength 617-625nm, Brightness 697.5-1162.5 mcd

· Green: Wavelength 525-535nm, Brightness 1387.5-1950 mcd

· Blue: Wavelength 460-470nm, Brightness 240-450 mcd
(Note: Brightness tolerance is ±10%, and dominant wavelength tolerance is ±1.0nm.)

Data Transmission and Protocol

The IC employs a unipolar zero-code protocol. Each symbol begins with a high level, and the duration of this high level determines whether the bit is a "0" or a "1".

Timing Specifications

· Symbol Period (T): 1.20 μs (Minimum 0.9 μs, Maximum 20 μs).

· "0" Code: High-level time 0.30 μs (range 0.20-0.40 μs); Low-level time 0.90 μs (range 0.70-20 μs).

· "1" Code: High-level time 0.90 μs (range 0.70-1.00 μs); Low-level time 0.30 μs (range 0.20-20 μs).

· Reset Code: Low-level time must be greater than 200 μs to reset the data pipeline.

Data Structure

Data is transmitted in 24-bit packets, sent most significant bit (MSB) first, in GRB order (G7→G6→...→G0, R7→R6→...→R0, B7→B6→...→B0). The first group of data sent by the MCU is automatically reshaped and forwarded to subsequent LEDs in the cascade.

Conclusion

The SK6803-T52491H4RGBP6-VC-E-A-002 is a robust, high-performance intelligent RGB LED solution. Its integration of the driver IC, support for 24V operation, and reliable single-line cascading protocol make it an excellent choice for designers looking to implement complex, large-scale lighting effects in consumer electronics and decorative lighting applications.
