NCP1093/D

NCP1093, NCP1094

Integrated IEEE 802.3at

PoE-PD Interface Controller

Description

The NCP1093 and NCP1094 are members of ON Semiconductor’s

high power HIPO

t 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.

The NCP1093 and NCP1094 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 NCP1093 and NCP1094 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.
