New standards and proprietary approaches are enabling the next generation of Power-over-Ethernet (PoE) systems capable of delivering up to 100 W to each powered device (PD). Large screen LCD displays, 3G / 4G / Wi-Fi hot-spots and pan-tilt-zoom CCTV cameras, for example, are placing increased demands on the power sourcing equipment (PSE) in terms of “soft-start” procedures, resilience to short-circuits, thermal management and power density. Part of Nexperia’s “NextPower Live” MOSFET portfolio, the PSMN075-100MSE has been designed specifically to compliment the latest PoE controllers, offering both superior linear mode operation and very low R_DS(on) in a cost-effective, industry compatible, LFPAK33 package.
