TL3701 Pspice model issue

Other Parts Discussed in Thread: TINA-TI, TLV3701

Hello,

I'm Anesh, working at Robert Bosch, India. For one of our application we have selected TL3701 to validate. We tried to use pspice model downloaded from TI in Orcad for simulation. But during simulation we get an error "ERROR(ORPSIM-15108): Subcircuit TLV3701 used by X_U3 is undefined". Please help us to locate the issue or correct the model if it has errors. We cannot use Tina-TI since we have constructed all the other circuits in Orcad.

Thank you, Anesh S.

    Anesh,

    The error you are seeing is due to the fact that you have not properly defined the TLV3701 model. The .lib file must be in your library path to be seen when the netlist is created for simulation. The .olb file can be placed, but you must update your .sim profile to include the .lib file.

    In Orcad/Allegro, you can do this by selecting the PSpice-->Edit Simulation Profile. Choose the Configuration files tab, select Library and Browse to find the location of the .lib file. Hit Add to Design and the library should then be found by the netlister.
