Overview

The SK6805-T52491H4RGBWP6-HV-XW-E-A-00X is a highly integrated, top-face luminescent SMD (Surface-Mount Device) RGBW LED produced by Shenzhen Normand Electronic Co.,Ltd This advanced component combines high-quality RGB and White LED chips with an integrated control IC (the 68-series SK6805) into a single, compact 6-pin package. Designed for a 12V operating environment, it provides a streamlined and efficient solution for dynamic lighting and consumer electronics requiring both vibrant color and high-quality white light output.

Key Features

· Operating Voltage & Current: 12V @ 5mA (OUT RGB), 12V @ 12mA (OUT W).

· 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 is 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 and fluorescent powder 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).

· Compliance: Fully RoHS and REACH compliant.

Applications

This versatile LED component is primarily targeted at the consumer electronics market (SMT), 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: VDD (Power Supply, 12V)

· 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℃)

· Logic Supply Voltage (VDD): 9V to 13.5V.

· Output Drive Current: 5mA typical for RGB, 12mA typical for W (VDS=1.0V).

· PWM Frequency: 4.0 KHz typical.

· Static Power Consumption: 0.29mA (VDD=5V, outputs off).

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

· Storage Temperature: -40℃ to +80℃.

Optical Parameters

The LED delivers bright and consistent illumination across the RGBW spectrum. The product is available in three white light color temperature variants:

· Red: Wavelength 617-625nm, Brightness 815-1275 mcd

· Green: Wavelength 525-535nm, Brightness 1500-2100 mcd

· Blue: Wavelength 465-475nm, Brightness 280-515 mcd

· White (BW): Color Temperature 5500-10000K, Brightness 3850-5800 mcd

· White (NW): Color Temperature 3600-4500K, Brightness 3850-5800 mcd

· White (WS): Color Temperature 2800-3200K, Brightness 3625-5312.5 mcd
(Note: Brightness tolerance is ±10%, dominant wavelength tolerance is ±1.0nm, and color temperature tolerance is ±100K. Ra > 80±2.)

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 32-bit packets, sent most significant bit (MSB) first, in GRBW order (G7→G6→...→G0, R7→R6→...→R0, B7→B6→...→B0, W7→W6→...→W0). The first group of data sent by the MCU is automatically reshaped and forwarded to subsequent LEDs in the cascade.

Conclusion

The SK6805-T52491H4RGBWP6-HV-XW-E-A-00X is a robust, high-performance intelligent RGBW LED solution. Its integration of the driver IC, support for 12V 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.
