MBI5170 - Macroblock

MBI5170 8-Bit Constant Current LED Sink Driver

MBI5170 succeeds MBI5168 and also exploits PrecisionDrive™ technology to enhance its output characteristics. Furthermore, MBI5170 uses the idea of Share-I-O™ technique to make MBI5170 backward compatible with MBI5168 in both package and electrical characteristics and extend its functionality for run-time LED current gain control in LED display systems. MBI51.

Features

z Compatible with MBI5168 in package and electrical characteristics z Exploit Share-I-O™ technique to provide two operation modes: Normal Mode with the same functionality as MB5168, Current Adjust Mode to program output current gain z 8 constant-current output channels z Output current adjustable through an external resistor z Constant output current range: 5 -120 mA z Excellent output current accuracy, between channels < ±3% (max.), and between ICs < ±6% (max.). z Constant output current invariant to load voltage change z Fast response of output current, OE (min.): 200 ns @Iout < 60mA OE (min.
