Description
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.
The NCP1090, NCP1091 and NCP1092 are fabricated in a robust high voltage process and integrates 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 NCP1090, NCP1091 and NCP1092 complement ON Semiconductor’s ASSP portfolio in industrial devices and can be combined with stepper motor drivers, CAN bus drivers and other high−voltage interfacing devices to offer complete solutions to the industrial and security market.
