  • TPS2376-H: Spacing Requirement for 60V IEC60950

    TI Thinks Resolved
    Part Number: TPS2376-H Other Parts Discussed in Thread: TPS2376HEVM Tool/software: Team, Could you please explain more about the layout guide from the datasheet "Spacing consistent with safety standards like IEC60950 must be observed between the 48-V…

  • TPS2376-H: Can I use only the UVLO function to turn on the PD at 22V without mounting RDet and Rclass?

    TI Thinks Resolved
    Part Number: TPS2376-H Tool/software: Hi, If I use a non IEEE compliant PSE , can I use only the UVLO function to turn on the PD at 22V without mounting RDet and Rclass? Then when I use a IEEE compliant PSE, Rdet and Rclass need to be mounted. Thank you…

  • RE: TPS2376-H: TPS2376-H Has no output and cannot shake hands with the device

  • TPS2376-H: PD not getting past detection stage of PoE Handshake

    Resolved
    Part Number: TPS2376-H I have a custom designed PD using TPS2376-H. I implemented only Mode B PoE whereby power can only be delivered over spare pins since this part will only go into my own system. I have a switch that can operate in Mode B. (Ultimately…

  • TPS2376-H: TPS2376H VDD-VSS VOLTAGE DROP

    Resolved
    Part Number: TPS2376-H I am having difficulty getting a dc voltage with PoE switch. I checked the V(VDD-VSS) output of tps2376h with a scope using tps2376h and 1-2250024-1 Ethernet connectors. The voltage reaches 54v through detection and classification…
