Part Number: DRV8876-Q1

Hi TI.

I am using DRV8876-Q1 Pspice Model in LT Spice Software, I am Getting an Error on DRV8876-Q1 model.

Please Suggest a solutions. 

ERROR:

    Hi Arun,

    I was able to run this model in PSpice for TI without a problem. So, there doesn't appear to be any issues with the model per se.

    I can't comment on what or why LTSpice is having an issue with these statements.

    If you can find out from them what is invalid (seems like it might be the '{' and '}', you can modify the model and re-run it.

    It won't be recognized by PSpice for TI as a TI model any longer, so I'd make sure to rename it, or have a separate version in case you want to compare circuit performance between tools.

    Regards,

    David
