Features

AI Translation
  • Simple interface for Power Over Ethernet (PoE) Powered Devices (PDs)
  • Includes PoE detection and classification circuits for all classes (0, 1, 2 and 3)
  • Compliance to IEEE802.3af PoE standards verified by University of New Hampshire Interopability Consortium (UNH-IOC)
  • Includes under voltage lockout (42 VDC on, 34 VDC off)
  • For Class 0, remove components VR31, R32, R33, R34, R35, Q31, Q32, Q33, Q34 and U31
  • R34 values: Class 1, R34 = 133 Ω; Class 2, R34 = 68.9 Ω; Class 3, R34 = 45.3 Ω
  • It is possible to use either bipolar transistor or MOSFET passswitches (Q35)
  • The bias current source (Q31) is used to allow the classification current source to be turned - off for minimal power loss once input voltage exceeds 28 VDC
