NCP1081: Integrated PoE-PD and DC-DC Converter Controller, 40 W

The NCP1081 is a member of ON Semiconductor's high power HIPO™ Power over Ethernet Powered Device (PoE-PD) product family and represents a robust, flexible and highly integrated solution targeting demanding medium and high power Ethernet applications. It combines in a single unit an enhanced PoE-PD interface fully compliant with the IEEE 802.3af and IEEE 802.3at (Draft 3.0) specifications and a flexible and configurable DC-DC converter controller.The NCP1081's exceptional capabilities offer new opportunities for the design of products powered directly over Ethernet lines, eliminating the need for local power adaptors or power supplies and drastically reducing the overall installation and maintenance cost.ON Semiconductor's unique manufacturing process and design enhancements allow the NCP1081 to deliver up to 25 W for the IEEE 802.3at (Draft 3.0) standard and up to 40 W for proprietary high power PoE applications. The NCP1081 is IEEE 802.3at (Draft 3.0) compliant and implements a Two Event Layer 1 classification. Additional proprietary classification procedures support high power power sourcing equipment (PSE) on the market. The unique high power features leverage the significant cost advantages of PoE-enabled systems to a much broader spectrum of products in emerging markets such as Industrial Ethernet, PTZ and Dome IP cameras, RFID, MIMO WLAN access points, notebooks, etc.The NCP1081 is fabricated in a robust high voltage process and integrates a rugged vertical N-channel DMOS with a low loss current sense technique suitable for the most demanding environments and capable of withstanding harsh environments such as hot swap and cable ESD events.
