NCP1090, NCP1091,
NCP1092
Integrated IEEE 802.3af
PoE-PD Interface Controller
Description
The NCP1090, NCP1091 and NCP1092 are members of
ON Semiconductorâs high power HIPOt Power over Ethernet
Powered Device (PoEâPD) product family and integrate an IEEE
802.3af PoEâPD 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 DCâDC controller. In addition, the
NCP1091 offers a programmable underâvoltage 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 Nâchannel
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 Semiconductorâs ASSP portfolio in industrial devices and can be
combined with stepper motor drivers, CAN bus drivers and other
highâvoltage interfacing devices to offer complete solutions to the
industrial and security market.
