TM5020C Is the driver IC designed by LED display panel. It has built-in CMOS displacement register and

lock memory function. Its core integrates the displacement register and lock memory mechanism of CMOS

technology, realizing the efficient conversion from serial data input to parallel data output. The chip has 16

current sources built in, and each output port stably provides a current between 3 and 36 ma to drive the LED

element. These output ports support a parallel configuration to increase the output current, and their

performance is highly stable to environmental changes, ensuring the accuracy of the current output. In

addition, TM5020C is also designed to have a flexible current regulation function, through the external

resistance of different resistance values (REXT), the user can accurately adjust the current intensity of each

output port, so as to achieve careful control of LED light emitting brightness. This product has excellent

performance and reliable quality.
