NS8808 DC12V Pixel LED Chip replace WS2815

NS8808 DC12V Pixel LED Chip, it is same protocol with ws2815, the only one pixel LEDs can replace ws2815 directly at this moment, and it is more stable than ws2815 after long time tested.
DC12V Dual-signal wires version, signal break-point continuous transmission. Any pixel's failure won't affect signal transfer and total emitting effect.

      The NS8808 is a 3-channel constant current LED drive with resumable data transfers and internal display patterns.  There are three open-drain constant current outputs, with a build-in PWM of grayscale. The range of input power is from +9V to +15V, and voltage-endurance of LED port is +12V. There is a built-in 12bits GAMMA correction module. PWM maximum refresh frequency is 8Khz, the GE8808B use the e-RZ (extended return to zero code)as the signal transmission mode,which can control the output current channel by channel and cascade infinitely,it provides two-signal data input as redundant control, which ensures the transmission of the signal if any single chip damages.In the displays the built-in display patterns that is suitable for those applications without a controller. There is the built-in power-on and power-off protection in the drive,which can enhance the service life of the chip. It alsohas the automatic test function while power on, working environment is from -40 ° C to + 85 ° C.
