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.
