I am trying to simulate with "PSpice for TI" a driving circuit with driver UCC21750 but this model is not in the TI library.
Using the model from the TI website triggers the ORCAP-15098 limitation for importing models with transistors and diodes. This limitation makes it very difficult to obtain enough waveforms to evaluate the performance.
Is ther any possibility to update the libraries to include the UCC21750 model in order to overcome this limitation??
BTW: is there any model included in the libraries that could ve similar to UCC21750??
Regarding the inclusion of UCC21750 in PspiceTI library, you can try putting this request with TI.
As an alternate you can explore UCC21710 which is available with PSpiceTI libraries. This is quite similar to UCC21750.
Thanks for the recommendation; but unfortunately this device (UCC21710) has the same model as UCC21732 which does not include the desat option (which ucc21750 has).
I want to simulate this feature as the protection against shortcircuits is handled diferently in the 21710-21732 (OC pin) and in the 21750 (DESAT pin).
I've had the same problem when using parts outside of the "PSpice for TI" libraries. You're limited to three signals per run but if you save the Probe data in a <newfile>.dat you can append it to a subsequent run of three different signals and display all six on one plot. Give it a try; I've done this for 9 traces already. One drawback is if your run takes awhile to complete this would be time consuming.
