Product Description

SCT2512 is designed as a current driver for the LED displays. It drives up to twelve

LED clusters with regulated constant current for uniform intensity. In applications,

three external resistors connected to pins of R^EXT0、R^EXT1 and R^EXT2 are used to

set the constant output current of OUT [0:3]、OUT [4:7] and OUT [8:11]

respectively in range from 5mA to 50mA.

The SCT2512 guarantees each output can endure maximum 17V DC voltage

stress. The built-in shift registers and data latches making the SCT2512

effective solution in driving LED display. Since the serial data input rate at can

reach to 20MHz, the SCT2512 will satisfy system which needs high volume

data transmission to control the LED display.
