1 / 12 page © Semiconductor Components Industries, LLC, 2014 March, 2014 − Rev. 2 1 Publication Order Number: NCP1093/D NCP1093, NCP1094 Integrated IEEE 802.3at PoE-PD Interface Controller Description The NCP1093 and NCP1094 are members of ON Semiconductor’s high power HIPO t 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. Features • Fully Supports IEEE 802.3af/at Specifications • Programmable Classification Current • Support Two Event Classification−Signature • Adjustable Under Voltage Lock Out (NCP1094 Only) • Open−Drain Power Good Indicator • 120 mA Typical Inrush Current Limit • 680 mA Typical Operational Current Limit • Pass Switch Disabling Input for Rear Auxiliary Supply Operation (NCP1094 Only) • Over−temperature Protection • Industrial Temperature Range −40°C to 85°C with Full Operation up to 125 °C Junction Temperature • 0.6 W Hot−swap Pass−switch • Vertical N−channel DMOS Pass−switch Offers the Robustness of Discrete MOSFETs http://onsemi.com PIN CONFIGURATION (Top View) RTN PGOOD * VPORTP CLASS DET INRUSH 1 VPORTN1 DFN10 MN SUFFIX CASE 485C Device Package Shipping† ORDERING INFORMATION NCP1093MNG DFN10 (Pb−Free) 120 Units / Tube †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D. *NCP1093 = UVLO NCP1094 = AUX ** Exposed pad should be connected to VPORTN NCP10 93MN ALYWG G NCP109xMN = Specific Device Code A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb−Free Package (Note: Microdot may be in either location) MARKING DIAGRAMS NCLASS_AT VPORTN2 NCP10 94MN ALYWG G NCP1093MNRG DFN10 (Pb−Free) 3000 / Tape & Reel NCP1094MNG DFN10 (Pb−Free) 120 Units / Tube NCP1094MNRG DFN10 (Pb−Free) 3000 / Tape & Reel EP** |
