TPS7H1101A-SP: Issues with SPICE model

Part Number: TPS7H1101A-SP
Other Parts Discussed in Thread: TPS7H1101-SP

Hello,

Can I get confirmation that the provided SPICE model in the Design Tools section works? I've downloaded the TPS7H1101A-SP PSPICE model and imported it both into SIMetrix and LTSpice and am receiving the following errors:

 I am unable to use the PSPICE for TI software for this design, would like to get this working in SIMetrix ideally. Thanks! 

  • Hi Natan,

    These errors usually pop up due to syntax differences between PSpice and other simulators. I'll take a look at the model today and work on getting these resolved. In the meantime, can you confirm this is the model you're using:

     

    Thanks,

    Sarah

  • Hey Sarah, 

    Yes I'm specifically using that model, though I also had errors running the TPS7H1101-SP model without the A. Getting the TPS7H1101A-SP to work would be greatly appreciated.

    Thanks!

  • Hi Sarah,

    Just checking to see if you had gotten a chance to work on the SIMetrix/LTSpice compatible SPICE model for this device? Is there anyway I could be provided with a working model by this week? 

    I'm intending to wrap up and deliver prelim designs by the end of next week. We are planning to begin configuration and test of the EVMs for this part. 

    Best regards,

    Nate

  • Hi Nate,

    Thanks for confirming which model you are using - I'm currently evaluating it.

    Thanks for letting me know your timeline. I can't say for sure what the timeline for a fix would look like until I'm able to confirm what the sources of the errors are, but I understand you're on a bit of a tight schedule and will have an update for you by the end of the day.

    Thanks,

    Sarah

  • Hi Nate, 

    I believe I've identified the problems and have sent you a friend request to discuss further.

    Thanks,

    Sarah
