Introduction
The LM5066IEVM-626 evaluation board provides the design engineer with a fully functional intelligent
monitoring and protection controller board designed for positive voltage systems. This user’s guide
describes the various functions of the board, how to test and evaluate it, and how to use the GUI design
tool to change the components for a specific application. To use the advanced telemetry and monitoring
capabilities of this device, the user must install the Intelligent Power Manager GUI; however, the LM5066I
is capable of acting as a hot-swap and protection circuit without any software installation. For the latest
software information, check the LM5066I High Voltage System Power Management and Protection IC with
PMBus data sheet (
