Einkanal-Power-over-Ethernet-Controller vereinfacht PSE-Design

(PresseBox) (Milpitas, California (USA), )
Linear Technology Corporation präsentiert den LTC4263, einen autonomen, einkanaligen PSE- (Power Sourcing Equipment) Controller mit integriertem MOSFET für Anwendungen in IEEE-802.3af-Power-Over-Ethernet- (PoE) konformen Systemen. Das IC ergibt zusammen mit einigen wenigen externen Bauteilen eine vollständige Einkanal-PSE-Lösung, die angeschlossene PDs (Powered Devices) erkennt, klassifiziert und mit einer potenzialgetrennten 48-V-Betriebsspannung versorgt. Der LTC4263 kann mittels standardkonformer AC- oder DC-Methoden erkennen, wenn ein PD abgetrennt wird, und verfügt über ausgeklügelte Steuerungsalgorithmen, die ihm einen autonomen, prozessorunabhängigen Betrieb ermöglichen.

Der LTC4263 enthält einen Strommesswiderstand für präzise Einschaltstrommessung, Strombegrenzung und Kurzschlussschutz und erfüllt dadurch alle Anforderungen des Standards IEEE 802.3af. Die Strombegrenzung kann so ewieaxgokewk ddhjol, blgx anl jlgv oeizzvhxhux ywv dkeyjmbfb QV-Vecfye utizcbo.
