NCP1093, NCP1094
Integrated IEEE 802.3at
PoE-PD Interface Controller
Description
The NCP1093 and NCP1094 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.
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.
