SAN JOSE, Calif., Dec. 5 /PRNewswire/ -- Designed for large outdoor LED video displays, providing 14-bit control of up to 16 channels, the MIC5400 is now available from Micrel Semiconductor (Nasdaq: MCRL), an industry leader in analog and broadband communications integrated circuits.
The MIC5400 is a digitally programmable LED display driver with 16 outputs arranged in two banks of eight channels. Each bank has 4-bit brightness control and each output has 10-bit intensity control. The MIC5400 incorporates a full suite of protection features including over temperature shutdown, power-on reset, open-fault protection, soft-start and watchdog.
``With this device were are addressing the specific needs of large-scale LED video displays'' said Scott Brown, Linear and RF Business Unit Manager ``We have incorporated a lot of features to ensure high performance and reliable operation.''
The MIC5400 is designed for multiple devices to be daisy-chained together and to minimize the effects of power supply transients and EMI. The MIC5400 incorporates an 8.3ns delay between the switching of each output, and each MIC5400 has a semi-random time delay to ensure that multiple MIC5400s within a system do not switch concurrently.
