Catalyst Semiconductor, Inc. has fortified its lineup of LED drivers with the introduction of the first member of a new family tailored for large LED video displays. The CAT4016 is a 16-channel, constant-current sink LED driver designed for billboard, marquee, instrument and other larger, general-purpose LED displays in both indoor and outdoor applications.

The CAT4016 LED channels can operate with an output voltage as low as 0.4 V (for 2mA to 100mA LED current), to enable more power-efficient designs. The maximum LED current is set by an external resistor. A high-speed, four-wire serial interface with up to a 25MHz clock frequency controls each individual channel using a shift register and latch configuration. A serial output data pin allows multiple devices to be cascaded and programmed via one serial interface. The CAT4016 also features a thermal shutdown protection function to disable the LED outputs if the die temperature exceeds a set limit.

The CAT4016 is available in a range of package options including 24-lead SOIC, TSSOP, QSOP and TQFN (4mm x 4mm) and sells for Rs.21.84 ($0.54) each in quantities of 10,000. Samples are now available, with projected lead time for production quantities currently at six to eight weeks.
