0, NCP1091 and NCP1092 are members of ON Semiconductor’s high power HIPOt Power over Ethernet Powered Device (PoE−PD) product family and integrate an IEEE 802.3af PoE−PD interface controller. The 3 variants all incorporate the required functions as such detection, classification, under voltage lockout, inrush and operational current limit. A power good signal has been added to guarantee a good enabling/disabling of the DC−DC controller. In addition, the NCP1091 offers a programmable under−voltage while the NCP1092 provide an auxiliary pin for applications supporting auxiliary supplies.
