    The GE8808B 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.
