简单介绍
MBI5171 exploits PrecisionDriveTM technology to enhance its output characteristics. Furthermore, MBI5171 uses the idea of Share-I-O? technology to make MBI5171 backward compatible with MBI5168 in both package and electrical characteristics. In addition,MBI5171 extends its functionality to provide one Special Mode in which two functions
are included, Error Detection and Current Gain Control, by means of the Share-I-O? technique on pins LE and, without any extra pins without adding any extra pin and without changing the printed circuit board originally designed for conventional LED drivers.
MBI5171 contains an 8-channel shift register and an 8-bit output latch, which convert serial input data into parallel output format. At MBI5171 output stages, eight regulatedcurrent ports are designed to provide uniform and constant current sinks with small skew between ports for driving LEDs within a wide range of forward voltage (Vf) variations. The excellent output accuracy is within ±3% between channels and within ±6% between ICs.

Feature
Compatible with MBI5168 in package and electrical characteristics
Exploiting Share-I-O? technique to provide two operation modes:
1.Normal Mode with the same functionality as MB5168
2.Special Mode to detect individual LED errors, like MBI5169 and program output current gain, like MBI5170
8 constant-current output channels
Constant output current invariant to load voltage change
Constant output current range: 5 -120 mA
Excellent output current accuracy, between channels: < ±3% (max.), and
between ICs: < ±6% (max.)
Output current adjusted through an external resistor
Fast response of output current,
(min.): 200 ns @Iout < 60mA
(min.): 400 ns @Iout = 60~100mA
Applications
﹡Message Signs
﹡Outdoor LED Video Displays
﹡Indoor LED Video Displays
