The LM5073 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-DC converter
are provided to allow freedom to select the best DC-DC
converter topology for the particular application.
