MBI5039 Description
MBI5039 is an enhanced 16-channel constant current LED sink driver with smart error detection and output current gain. MBI5039 succeeds MBI5026 and also exploits PrecisionDrive™ technology to enhance the output characteristics. Furthermore, MBI5039 adopts Share-I-O™ technology to be backward patible with MBI5026, MBI5027 and MBI5029 in pin definition and to extend the functionality for LED’s in-message error...
