Introduction
The LM5064EVK evaluation module provides the power design engineer with a fully functional intelligent
monitoring and protection controller board designed for negative voltage systems. This application note
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. Use of the advanced telemetry and monitoring
capabilities of this device requires the installation of the Intelligent Power Manager GUI; however, the
LM5064 is capable of acting as a hot-swap and protection circuit without any software installation. Please
check the LM5064 Negative Voltage System Pwr Mgmt & Protection IC with PMBus (
) for the
latest software and data sheet information.
