TM1818 LED drive integrated circuit 1818 IC
TM1818 is the driver IC of LED display panel design. It has built-in CMOS shift register and latch function, which can convert serial input data into parallel output data format. TM1818 has 16 current sources, which can provide a constant current of 2~60mA at each output port to drive LED. The output of each OUT drive channel can be shorted to get a larger current output, and when the environment changes, it has little influence on its output current. At the same time, external resistors with different resistance values (REXT) can be selected to adjust the current size of each output port of TM1818. Therefore, the LED luminance can be accurately controlled, suitable for high-quality white balance display drive module. This product has excellent performance and reliable quality.
