MBI5049数据手册Macroblock中文资料规格书

描述 Description

MBI5049 is an enhanced 16-channel constant current LED sink driver with advanced error detection functions and smart power-saving modes. MBI5049 features 0-power mode to reduce the consumed current by chip and increase the power efficiency. Therefore,
MBI5049 is especially suitable for LED traffic sign and message sign applications.
MBI5049 provides several kinds of error detections including LED open-circuit, leakage and over-temperature protection(160°C). This chip integrates a 6-bit current gain which can adjust the output current from 12.5% to 200%.
