FM6363 16-way EPWM Constant Current Output LED Driver IC
FM6363 is a driver chip specially designed for LED full-color display applications. FM6363 built-in 16-bit shift register can convert serial input data into grayscale pixels of each output channel. The current value output by the 16 constant current output channels of FM6363 is not affected by the load voltage at the output end, provides a consistent and constant output current, is not affected by the PCB board, and has excellent anti-interference. FM6363 can not only adjust the current of each output stage by external resistors with different resistance values, but also can adjust the FM6363 channel current gain by software to control the brightness of the LED display. FM6363 adopts Fuman EPWM patented display technology, and adopts intelligent pulse width modulation function, which enhances the low-gray visual effect.
FM6363 can support up to 64 LED scanning screens; through technological innovation, it can effectively solve problems such as low gray blocks, color cast, pitting, dark first line, high contrast coupling, cross-page color difference; through real-time error detection function, FM6363 can independently detect whether each LED is open circuit without adding additional external components; FM6363’s novel function of eliminating cross phenomenon solves the caterpillar phenomenon caused by LED dead pixels. In addition, the built-in blanking/clamping circuit of FM6363 cooperates with different configuration bits, which can greatly enhance the ability of blanking/clamping, and effectively solve the phenomenon of upper and lower ghost images and text ghost images; Greatly improve various display defects such as cross-version coupling, high-contrast, and medium-contrast coupling; there is also a black screen energy-saving function to reduce power consumption when the screen is black.
