Catalyst launches new LED drive products

October 3rd, Catalyst semiconductor company launched a large screen LED panel market launch of new products CAT4016. The new CAT4016 is a 16 channel, constant current source LED driver designed specifically for billboards, advertising titles, instrumentation, or other large, general purpose indoor and outdoor LED displays.

The LED channel of CAT4016 can maintain steady state when the output voltage is low to 0.4V, which can achieve higher power efficiency in the application design. LED current can be set by external resistors. A high speed, four wire serial interface with a frequency of up to 25MHz controls each LED channel through a shift register and latch architecture. Independent serial data output pin allows multiple devices to be connected in series using the same serial interface. CAT4016 also has a thermal protection feature that allows the device to shut down the LED output when the chip temperature exceeds the allowable limit. As can be used to replace Macroblock, Toshiba devices or other manufacturers of similar products, CAT4016 provides more kinds of packages for the user, including 24 pin SOIC, TSSOP, QSOP and TQFN area is only 4 x 4mm package.
