The TPS2384 is a quad-port power sourcing equipment power manager (PSEPM) and is compliant to the Power-over-Ethernet (PoE) IEEE 802.3af standard. The TPS2384 operates from a single 48-V supply and over a wide temperature range (–40°C to 125°C). The integrated output eliminates two external components per port (FET and sense resistor) and will survive 100-V .
