NCP1091DRG General Description

The NCP1090, NCP1091 and NCP1092 are members of ON Semiconductor’s Power over Ethernet (PoE) Powered Device (PoE−PD) product family and integrate an IEEE802.3af certified interface controller.

The 3 variants incorporate all the required functions, such as detection, classification, under voltage lockout, inrush and operational current limit. A power good signal has been added to guarantee correct enabling/disabling of the DC−DC convertor. In addition, the NCP1091 offers a programmable under−voltage while the NCP1092 provides an auxiliary pin for applications supporting auxiliary supplies.

The NCP1090, NCP1091 and NCP1092 are fabricated in a robust high voltage process and integrate a rugged vertical N−channel DMOS suitable for the most demanding environments and capable of withstanding harsh environments such as hot swap and cable ESD events.

The functionality of the NCP1091 can be tested using the NCP1090GEVB Evaluation Board (excepting the adjustable UVLO feature).
