OrCAD symbol and PSpice model for TPS60403, TPS7325, TLV3404 and ISO7521C

Other Parts Discussed in Thread: TPS60403, ISO7521C, TLV3404, TLV3401, TPS60402, TPS60401, TPS60400

             Looking to do simulations on PSpice, I need  OrCAD symbols and PSpice model for the TPS60403, TPS7325, TLV3404 and ISO7521C and I have not been able to locate it on this web site.

 Anyone have a model they could share.

  • Fethi,

    The TLV3404 is a quad device in a product family that includes the single-channel version, the TLV3401.
    They will share the same model; it was an oversight on our part for not making the model available on the TLV3404 product page.
    The TLV3401 Orcad/Cadence model and symbol available on the device product page at:

    The file will unzip into an entire Cadence project  that features the device netlist model (.lib file) and symbol (.olb file), a test circuit schematic and sim profiles for a transient sim and a temp sweep.

    The ISO7521C is a digital isolator; we traditionally do IBIS models rather than Spice models for devices with digital I/O.
    An IBIS model is available at:

    I was unable to find models for te TPS devices in our database. I will check with our power modeling team to find out if these models are in design.



  • Fethi,

    I was able to find only the TPS60403  Orcad Symbols and associated Cadence DBV package  footprints.  The group within TI that generated the symbols  uses a generic symbol to cover the different frequencies (TPS60400, TPS60401, TPS60402, TPS60403).  The Value is generated from TI database when placing the symbol. 


    Sorry that we do not have Symbols and Footprints for the TLV3404, ISO7521C or TPS7325 parts.  We are in the process of kicking off a new Symbols and Footprints project  that will provide all active parts on with Symbols and Footprints.



  • Hi

    Thanks a lot for your detalied reply.
