AX6958／MAX6959 is a four bit and 9 sections driver.MAX6958／MAX6959 uses six PWM(64 rank) brightness control technology, which can adjust all the average working current of LED at the same time.The single pixel level (LED) control can be achieved by expanding MAX6958 / MAX6959 function.MAX6958 / MAX6959 adoptes multiplexing technique of less pins, the 36th section drvier only uses 10 drive pins.The MAX6958 / MAX6959 standard driver connecting way is showed as the table.The MAX6958 / MAX6959 pins and LED connecting ways are different from standard connecting methods.According to the different time slot of multiplex cycle,MAX6958／MAX6959 4～7 pins act as cathode and anodic dirvers. MAX6958／MAX6959 uses four multiplexing driving plans to drive four groups of LED cathodes in turns and every group has 9 LEDs.
