Beschreibung
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 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 voltageprocess and integrate a rugged vertical N−channel DMOS suitable forthe most demanding environments and capable of withstanding harshenvironments such as hot swap and cable ESD events.The NCP1093 and NCP1094 complement ON Semiconductor’sASSP portfolio in industrial devices and can be combined with steppermotor drivers, CAN bus drivers and other high−voltage interfacingdevices to offer complete solutions to the industrial and securitymarket.
