NCP1093, NCP1094 Integrated IEEE 802.3at PoE-PD Interface Controller Description The NCP1093 and NCP1094 are members of ON Semiconductors high power HIPO Power over Ethernet Powered Device (PoEPD) www.onsemi.com product family and integrate an IEEE 802.3at PoEPD interface controller. Both variants incorporate the required functions such as detection, DFN10 classification, under voltage lockout, inrush and operational current MN SUFFIX CASE 485C limit. A power good and NCLASS AT signal have been added to guarantee proper enabling/disabling of the DCDC controller for both typeI and typeII operation. In addition, the NCP1093 offers a PIN CONFIGURATION programmable undervoltage while the NCP1094 provides an 1 INRUSH VPORTP auxiliary pin for applications supporting auxiliary supplies. CLASS NCLASS AT The NCP1093 and NCP1094 are fabricated in a robust high voltage DET EP** * process and integrate a rugged vertical Nchannel DMOS suitable for VPORTN1 PGOOD the most demanding environments and capable of withstanding harsh RTN VPORTN2 environments such as hot swap and cable ESD events. (Top View) The NCP1093 and NCP1094 complement ONSemiconductors *NCP1093 = UVLO ASSP portfolio in industrial devices and can be combined with stepper NCP1094 = AUX motor drivers, CAN bus drivers and other highvoltage interfacing ** Exposed pad should be devices to offer complete solutions to the industrial and security connected to VPORTN market.
