General Description

The TPS2388 is an 8-channel power source equipment (PSE) controller engineered to insert power onto Ethernet cable according to IEEE 802.3at-2012 standard (or 802.3at).

The PSE controller can detect powered devices (PDs) that have a valid signature, determine the power requirements according to the classification, and apply power through either one (Type -1) or twoevent (Type-2) physical classification.

The TPS2388 also has the flexibility to support UPoE and other non-standard loads.
