APA107 LED chip, APA107 diode compare with APA102C/SK6812 diode

Product Overview

APA107 is a set of smart control circuit and a light emitting circuit in one of the controlled LED source. The outer type is the same with a 5050LED chip, each element is a pixel. Pixels contained within the intelligent digital interface data latch signal shaping amplification circuit, power supply circuit, a built-in constant current circuit, high precision RC oscillator, the output is driven by the patented PWM technology, effectively guarantee the pixels in the color of the light high consistency.


Data protocol using unipolar NRZ communication mode, the pixel is reset after the end of DIN, accept the data transmitted from the controller to the 24bit, the first to send data by the first pixel to pixel extraction, internal data latch, the remaining data after the internal plastic the processing circuit after shaping amplification through the DO port output began to turn to the next cascade of pixels, each pixel through a transmission signal, reduce. Pixel using automatic shaping forwarding technology, makes the number of cascade without signal

transmission limit of the pixel, only limited signal transmission speed.


The LED has a low driving voltage, environmental protection and energy saving, high brightness, scattering angle, good consistency, low power, long life and so on. The control circuit is integrated in the LED above, more simple circuit, small volume, easy installation.


Main Application Field:

● Full color LED string light, LED full color module, LED super hard and soft lights, LED guardrail tube, LED appearance / scene lighting

● LED point light, LED pixel screen, LED shaped screen, a variety of electronic products, electrical equipment etc..


Description:

● Top SMD internal integrated high quality external control line serial cascade constant current IC;

● control circuit and the RGB chip in SMD 5050 components, to form a complete control of pixel, color mixing uniformity and consistency;

●built-in data shaping circuit, a pixel signal is received after wave shaping and output waveform distortion will not guarantee a line;

●The built-in power on reset and reset circuit, the power does not work;

●gray level adjusting circuit (256 level gray scale adjustable);

● red drive special treatment, color balance;

● line data transmission;

● plastic forward strengthening technology, the transmission distance between two points over 10M;

●data transmission frequency up to 800Kbps, when the refresh rate of 30 frames per second, a cascade of not less than 1024;

● built-in powerpolarity protection module, powerpolarity will not damage.

The typical application circuit:

 

Compare with APA102C SK6812, the advantage of APA107,

 

1, Intelligent reverse connect protection, the power supply reverse connection does not damage the IC.

2, The control circuit and the LED share the only power source.

3, Control circuit and RGB chip are integrated in a package of 5050 components, form a complete control of pixel point.

4, Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.

5, Built-in electric reset circuit and power lost reset circuit.

6, Each pixel of the three primary color can achieve 256 brightness display, completed 16777216 color full color display, and scan frequency not less than 400Hz/s.

7, Cascading port transmission signal by single line.

8, Any two point the distance more than 5m transmission signal without any increase circuit.

9, When the refresh rate is 30fps, cascade number are not less than1024 points.

10, Send data at speeds of 800Kbps.

11,The color of the light were highly consistent, cost-effective..

Applications

12, Full-color module, Full color soft lights a lamp strip.

13, LED decorative lighting, Indoor/outdoor LED video irregular screen.
