The NCP1093 and NCP1094 are members of ON Semiconductor's high power HIPO Power over Ethernet Powered Device (PoE-PD) product family and integrate an IEEE802.3at 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 control of the DC-DC converter for both type-I and type-II operation. In addition, the NCP1093 offers programmable under voltage lockout 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 is 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.
