Intelligent reverse connection protection, power reverse connection not damage the IC. The control circuit and the RGB chip are integrated in a 3528 packaged component to form a complete external control pixel. The IC control circuit and the LED point light source share a power supply. Built-in signal shaping circuit, any pixel point receives the signal after waveform shaping and then output, to that waveform distortion not accumulate. Built-in power-on reset and power-down reset circuits.
