PoE power source equipment controllers engineered to insert power onto an Ethernet cable

Available now from Mouser is Texas Instruments' TPS2388 Eight-Port Power-over-Ethernet Power Source Equipment Controllers. These devices are engineered to insert power onto an Ethernet cable. Powered devices with a valid signature can be recognised by the PSE. The PSE controller also manages the power requirements according to the classification, and apply power through either one (Type 1) or two-event (Type 2) physical classification. UPoE and other non-standard loads are supported due to the flexibility of the device. Software migration from earlier generation PSE devices is simplified by port remapping, and the device pinout enables designers to create two-layer PCB designs. Designers can additionally balance efficiency, thermal, size, and solution cost demands with the external FET architecture. Up to eight levels of per port shutdown priority for applications needing the instant disabling of multiple ports is given by the fast shutdown (OSS) input. Typical applications include enterprise switches and routers, SoHo switches and routers, PoE pass-through power modules, and network video recorders.
