Product details

Description

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.Its user-friendly design allows the user to adjust the output current (5~60mA) by using an external resistor.The current also can be further tuned by 6-b
