MBI5034 Overview
MBI5034 is an enhanced 16-channel constant current LED sink driver with smart error detection and output current gain. MBI5034 succeeds MBI5026 and also exploits PrecisionDrive™ technology to enhance the output characteristics. Furthermore, MBI5034 adopts Share-I-O™ technology to be backward patible with MBI5026, MBI5036 and MBI5039 in pin definition and has the functionality for pulsory LED open-circuit detection and current gain control in LED display systems. With the open-circuit detection, MBI5034 can detect individual LED open-circuit error without extra ponents. Once the dedicated mand is issued, all of the output ports will be turned on with small current. Since the turn-on duration and current are so small, the flicker will not be sensed by human eyes and the image quality will not be impacted. All of the channels are detected no matter the input data is zero or one. - 1 - July...
