WS2814A RGBW Addressable LED Strip
WS2814A LED strip is an external-IC RGBW addressable LED strip designed for dynamic color effects with an additional white channel. Available in 12V and 24V configurations, WS2814A strips can be designed with different LED densities and pixel groupings for commercial, architectural and entertainment lighting projects.
TM1814 and SM16704 are alternative IC options with similar RGBW addressable functions, allowing customers to select the IC according to project requirements, cost and supply preference.
Compared with 5V individually addressable RGBW strips, higher-voltage external-IC designs can reduce voltage drop and are more suitable for longer installations.

WS2814A VS TM1814 VS SM16704
WS2814A, TM1814 and SM16704 are similar RGBW external-IC solutions for addressable LED strips, but each has slightly different electrical characteristics.
WS2814A is a common and stable choice for 12V and 24V RGBW pixel strips.
TM1814 offers more flexibility in output current adjustment, which can be useful for customized LED designs.
SM16704 provides similar RGBW addressable functions and is often used as an alternative IC depending on project requirements, controller compatibility and supply availability.
In most applications, all three can achieve similar RGBW lighting effects, while the final IC choice should be confirmed according to the strip circuit and controller.
WS2814A VS WS2814 Addressable LED Strip
WS2814A and WS2814 are both 4-channel RGBW addressable LED strip driver ICs with 256-level grayscale and high-speed serial data transmission, but their signal structures are different.
WS2814A uses a single data input and is a simpler solution for standard RGBW addressable LED strips, while WS2814 adds a second data input for backup signal transmission.
This breakpoint-resume design allows the signal to continue to downstream pixels if one IC fails, giving WS2814 better signal reliability for larger or more demanding lighting projects. Both ICs are commonly used in 12V and 24V RGBW addressable LED strips.

FAQS
The data protocol adopts a single line return to zero code communication method. After the chip is powered on and reset, the DIN end receives the data transmitted from the controller. The first 32bit data sent is extracted by the first chip and sent to the data latch inside the chip. The remaining data is processed and amplified by the internal shaping circuit, and then transmitted to the next cascaded pixel through the DO port. After each pixel transmission, The signal is reduced by 32 bits. The chip adopts automatic shaping and forwarding technology, so that the number of cascaded pixels is not limited by signal transmission, only limited by signal transmission speed requirements.
The data latch inside the chip generates different duty cycle control signals at the OUTR, OUTG, OUTB, and OUTW control terminals based on the received 32bit data. When waiting for the DIN terminal to input the RESET signal, all chips synchronously send the received data to each segment. The chip will receive new data after the signal is bundled, and after receiving the initial 32bit data, it will forward it to the data port through the DO port, Before the chip receives the RESET code, the original output of the OUTR, OUTG, OUTB, and OUTW pins remains unchanged until it reaches 280 μ After the low-level RESET code above s, the chip outputs the 32bit PWM data pulse width just received to the OUTR, OUTG, OUTB, and OUTW pins.
Provide 8 SOPs
main features
1) R, G, B, W output ports withstand voltage of 20V, and DIN ports withstand voltage of 9V.
2) The chip is equipped with a built-in voltage regulator, and 24V and below power supplies only need to connect a resistor to the IC VDD pin, without the need for an external voltage regulator.
3) Built in signal shaping circuit, any pixel receives a signal and undergoes waveform shaping before outputting, ensuring that line waveform distortion does not accumulate.
4) Built-in power on reset and power off reset circuits.
5) The PWM control terminal can achieve 256 levels of adjustment, with a scanning frequency of 2KHz.
6) Serial cascade interface, capable of receiving and decoding data through a single signal line.
7) There is no need to add any circuit when the transmission distance between any two points does not exceed 5 meters.
8) The color of light is highly consistent and cost-effective.

ws2814 led strip is better than tm1814 sm16704 ws2814a led strip
On the basis of TM1814/SM16704/WS2814A magic light strip, there is also WS2814 RGBW magic light strip now. WS2814 IC is equivalent to the upgraded version of TM1814/SM16704/WS2814A. It has all the performance of this ordinary RGBW, plus an additional breakpoint. With the function of resuming transmission, the damage to a single IC does not affect the quality of the subsequent light strips, so the performance is more stable.
