1094 are members of ON Semiconductor’s high power HIPOt Power over Ethernet Powered Device (PoE−PD) product family and integrate an IEEE 802.3at PoE−PD interface controller. Both variants incorporate the required functions such as detection, classification, under voltage lockout, inrush and operational current limit. A power good and NCLASS_AT signal have been added to guarantee proper enabling/disabling of the DC−DC controller for both type−I and type−II operation. In addition, the NCP1093 offers a programmable under−voltage while the NCP1094 provides an auxiliary pin for applications supporting auxiliary supplies.
