LM5073MH

The LM5073MH is a Powered Device (PD) Interface provides a high performance solution that is fully compliant to IEEE 802.3af for a PD connecting into Power over Ethernet (PoE) 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 applications up to twice the power level of IEEE 802.3af compliant devices. The 100V maximum voltage rating simplifies selection of the transient voltage suppressor that protects the PD from network transients. Control outputs for a separate DC to DC converter are provided to allow freedom to select the best DC to DC converter topology for the particular application.
