This is the ST PM880x series Power over Ethernet (PoE) interface, which has been engineered to simplify power supplies for all powered devices. The units encompass popular technology to transfer electrical power and data over an RJ-45 cable.
The unit is compliant with both the more recent IEEE 802.3at specification, commonly known as PoE+, and the former IEEE 802.3af (PoE). The unit combines all necessary functions demanded by the communications standard, which includes classification, undervoltage lockout (UVLO) and in-rush current limitation.
