Overview
NCP1090, NCP1091, NCP1092
Integrated IEEE 802.
3af
PoE-PD Interface Controller
Description The NCP1090, 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.
