Features z patible with MBI5168 in electrical characteristics and package z Exploiting Share-I-O™ technique to provide two operation modes: - Normal Mode with the same functionality as MB5168 - Special Mode to detect individual LED errors, like MBI5169 and program output current gain, like MBI5170 z 8 constant-current output channels z Constant output current invariant to load voltage change z Constant output current range: 5 -120 m A z Excellent output current accuracy, between channels: < ±3% (max.), and between ICs: < ±6% (max.) z Output current adjusted through an external resistor z Fast response of output current, OE (min.): 200 ns @Iout< 60m A OE (min.): 400 ns @Iout= 60~100m A z 25MHz clock frequency z Schmitt trigger input z 3.3~ 5V supply voltage z 256-step run-time programmable output current gain suitable for white balance application z Optional for “Pb-free & Green” Package Dual In-Line Package MMBBI5I510680C1CNN P-DIP16-300-2.54 Weight：1.02g MSm BBa II5l5l1O06u08t C1lin CDe DPackage SOP16-150-1.27 Weight：0.13g MWBid Ie5-1b6o8d Cy DSWOP BI5001CD SOP16-300-1.27 Weight：0.37g MSh Bri In5k16S8OCPP Current Accuracy Between Channels Between ICs < ±3% < ±6% Conditions IOUT = 10 ~ 100 m A, VDS = 0.8V, VDD= 5.0V Macroblock, Inc. 2005 Floor 6-4, No.18, Pu-Ting Rd., Hsinchu, Taiwan 30077, ROC. TEL: +886-3-579-0068, FAX: +886-3-579-7534, E-mail: info@mblock..tw - 1 - March 2005, VA.02 8-Bit Constant Current LED Driver with LED Error Detection and Run-Time Current Adjustment Product Description MBI5171 succeeds MBI5168 and also exploits Precision Drive™ technology to enhance its output characteristics. Furthermore, MBI5171 uses the idea of Share-I-O™ technology to make MBI5171 backward patible with MBI5168 in both package and electrical characteristics and extend its functionality for LED load Error Detection and run-time LED current gain control in LED display systems, especially LED traffic sign applications. MBI5171 contains an 8-bit Shift Register and an...
