UCC21521 Gate driver Pspice schematic model

[kaanaydin]

Hi my friends,
I downloaded the UCC21521 Unencrypted PSpice Transient Model from texas ins. website and then I added it in orcad library and I created a obl file from them in orcad.
But I have some questions because I am not good at with Orcad.

So, in the part section , when I chose the UCC21521 library I saw many parts in part list. How can I use them ? I read datasheets but I can not figure it out. I saw the all of parts in lib file but I have no idea to use them.


Thank you.

They may be "subsidiary" pieces used to create the top level,
maybe calling out specific models for specific roles etc. Have
you found which of the library members -is- the top level?

UCC21521_TRANS is main part. when I look the lib file, I saw that .SUBCKT UCC21521_TRANS is main part. But there is also something about the other parts in this code such as ;
that is the main code;

part code:


Can I use the directly UCC21521_TRANS part without use others ?

All of those subcircuit definitions need to be loaded for
netlisting to proceed properly. Whether this happens
"automagically", or you need to add the .include / .lib
for yourself in the main .cir file, I couldn't say.

Thank you for your reply, but I have no idea to use all of them in my circuit, I just need main UCC21521_TRANS model. Are there any way to combine them all together in one model ?
This is the netlist ;

You don't need to know, you just need to be sure they
are all "loaded" (.lib stmt) and that you instantiate the
top level. Top level refers to the rest and only has to be
able to find them.

Download the slum565. You have the .lib inside.
1) Open the OrCAD's Model Editor : type "modeled" in the "run" of Windows and press enter.
2) Click on the icon "Open library"
3) Select the .lib from the slum565 folder
4) Left click the model once it has been charged in the "model editor". The model's parameters will be displayed.
5) File -> Export to Capture Part library. Click OK in the next window in order to create the ".olb"
--CONTINUE THIS STEPS IF NO WARNINGS ARE SHOWN--
6) Open your project
7) When placing a part, add a new library. Add your ".olb"
8) Inside PSpice, go the the Model Editor tab -> "library" folder -> (right click) add file -> add your ".lib" -> "Schematic library" when they ask for it.
9) Copy the ".lib" file you just added and paste it into the "model libraries" folder under the PSpice resources.
10) DONE.
