DESCRIPTION
The LM5073 Powered Device (PD) interface provides a high performance solution that is fully pliant to IEEE 802.3af for a PD connecting into Power over Ethernet (Po E) networks. The LM5073 provides the flexibility for the PD to also accept power from unregulated auxiliary sources such as AC adapters and solar cells in a variety of configurations. The low RDS(ON) PD interface hot swap MOSFET and programmable DC current limit extend the range of LM5073...
