DM133 Datasheet PDF

SiTi DM133

The DM133 is a constant current driver specifically designed for LED display applications. The device includes a 16-bit shift register, two latches, and constant current drivers on a single Silicon CMOS chip. Its built-in open/short detection and thermal alarm circuits help the user to detect the overheating of the IC and LED failures.
