N Macroblock Ships MBI5171, Industry's First 8-bit LED Driver with Real-Time Error Detection and Current Adjustmen (May 14, 2004)
  Hsinchu, Taiwan, May 2004 - Macroblock, a dedicated analog IC design house , today released MBI5171, an advanced 8-bit LED driver with real-time error detection and current adjustment.

MBI5171 features 8 constant-current output channels with 128-step current adjustment and each channel can deliver constant current from 5mA to 120mA. Hence, the current skew between ICs can be compensated within 1%. Moreover, in the error detection mode, display applications need not be shut down and system controllers can read back each open or short LED error at any time. Such features can especially assist to manage outdoor and distant displays, like traffic sign applications and LED full-color display panels.

By means of the Share-I-O™ technique, an additional function, error detection or current adjustment, is added to MBI5171 without adding any extra pins in package. Thus, MBI5171 could be a drop-in enhancement of PrecisionDrive™ series and users need not change the printed circuit board originally designed for conventional LED drivers.
