TPS2384PAP

Product Summary

The TPS2384PAP is a quad-port power sourcing equipment power manager (PSEPM) and is compliant to the Power-over-Ethernet (PoE) IEEE 802.3af standard. The TPS2384PAP operates from a single 48-V supply and over a wide temperature range. The integrated output eliminates 2 external components per port (FET and sense resistor) and will survive 100-V transient. Four individual 15-bit A/D converters are used to measure port voltage, current and die temperature making PSE solution simple and robust. The TPS2384PAP comes with a comprehensive software solution to meet the most demanding application which can serve as a core for all PoE system designs. The applicaitons of the TPS2384PAP include Ethernet Enterprise Switches, Ethernet Hubs, SOHO Hubs, Ethernet Mid-Spans and PSE Injectors.
