Product Description
MBI5038 is an enhanced 16-channel constant current LED sink driver with advanced error detection functions and the smart power-saving mode.
MBI5038 provides “compulsory silent error detection”. Once the dedicated command is issued, all of the current output ports will be turned on in about 700ns interval with small current. The image will not be impacted since the turn-on duration and current are so small. MBI5038 may detect all of the current output ports and report the LED error status without comparing original data. Moreover, the settable threshold voltages for short-circuit detection and leakage diagnosis may comply with the variation of different LED forward voltage. Additionally, to ensure the system reliability, MBI5038 is built with thermal error flag to prevent IC from over temperature (160°C).Features
