DC12V Digital Pixel LED LC8808
The LC8808 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 gray scale. 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 LC8808 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.LC8808 provides two-signal data input as redundant control, which ensures the transmission of the signal if any single chip damages. In the absence of signal input,LC8808 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 also has the automatic test function while power on, which is convenient for the customer to test,The LC8808 provides SOP8 packaging, working environment is from -40 ° C to + 85 ° C.
