TPS1H100-Q1: PSpice model issue

Part Number: TPS1H100-Q1

Hello E2E team,

I want to test the behavior of our design using the TPS1H100A-Q1 high-side switch. Since I need to simulate the design with encrypted models, I have to use the PSpice model. Running the SLVMAI7A project in PSpice 17.4 gives me the output "ERROR(ORPSIM-15141): Less than 2 connections at node CL.". Adding an additional clamping resistor clears the error, but there is no CL current, and so there is no load current. Maybe it has something to do with CL been shown as an input pin? Interestingly, when using the .lib model with LTSpice, the TPS1H100A seems to work fine. Is there anything I can do to make the model work in PSpice?

Best Regards,

Niklas

    Hi Niklas,

    Welcome to E2E and thanks for coming here to share this issue.

    I'll take a look a the project files but would appreciate if you answer the following:

    • Aside from adding the clamping resistor, have you made any modifications to the schematic or the simulation profile when the error appears?
    • If modifications were made, would you be able to share a schematic that I can reference?
    • Does this occur if you don't use the project file and use the .OLB file and .LIB file in a separate project?

    Hi Anthony,

    thank you for your quick reply!

    • I have tied STB and the NC pins to GND. I just redownloaded the project for a reference without modifications, it generates the same error. I also downloaded the TPS1H100B project, which leads to the same error on the CL pin, aswell as an additional error on the CS pin.
    • The error also occures when using the .olb and .lib file in another project.

    Best Regards,

    Niklas

    Hi Niklas,

    Alrighty, that doesn't sound too good but helpful to know! I'll look further into the issue and let you know when they've been updated or directly update here.

    We appreciate the find!

    Hi Niklas,

    Would you be able to send me an email at a-pham@ti.com I have a working model that is unfortunately too large to attach in this post.
