FM6124DJ Overview:
FM6124DJ is a driver IC designed specifically for LED modules and displays, with 16 constant current output driving capabilities. The FM6124DJ adopts patented "output clamping" technology, which can effectively eliminate the phenomenon of first row dimming and prevent damage to the lamp beads. The FM6124DJ adopts an enhanced hidden feature design, which has excellent hidden effect. At the same time, FM6124DJ has excellent anti-interference characteristics, with constant current and low ash effects not affected by the PCB board. And different external resistors can be selected to adjust the current size of the output stage at will, accurately controlling the brightness of the LED.
FM6124DJ will cache 16bit display data during the display process (OE‘s falling edge), so the system can continue to store 16bit serial data during the FM6124DJ display process. Compared to the universal constant current source chip, the refresh rate can be increased by more than 50%.
The FM6124DJ adopts precise current control technology internally, which can reduce inter chip error to less than ± 3.5% and inter channel error to less than ± 2%.
