Application note:
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 two-event (Type-2) physical classification. The TPS2388 also has the flexibility to support UPoE and other non-standard loads.
The Port remapping and the device pinout allow designers to enable 2-layer PCB designs and simplify software migration from previous generation PSE devices. The external FET architecture allows designers to further balance size, efficiency, thermal, and solution cost requirements. The current foldback reduces thermal stress on the external MOSFETs during startup and overload conditions allowing the use of cheaper FETs.
The Fast Shutdown (OSS) input provides up to eight levels of per port shutdown priority for applications that require the immediate disabling of multiple ports.
