CSD19534Q5A: Model Question

Part Number: CSD19534Q5A
Other Parts Discussed in Thread: TINA-TI,

Dear *,

on web page http://www.ti.com/product/CSD19534Q5A/toolssoftware there are two models PSpice and TINA-TI.

1) Can you tell are the both models the same but in different format or is the Pspice from 2020 better?

2) If they are not the same which one is new-er or better?

3) can both models bu used in TINA-TI

4) Can you tell also are booth models ok for using in AC and Transient simulation ?

5) Can you tell do booth model model the input capacitance Cgs and Cgd?

6) Can you tell do booth model model the input gate charge Qg Qgd Qgs?

Best Regards.

    Hi David,

    Thanks for your interest in TI FETs.

    1. Both models were developed around the same time. Normally, TI develops the PSpice model first and then translates it into TINA-TI format. They should be essentially the same.
    2. The latest PSpice model in the product folder on TI.com is unencrypted but the TINA model is still encrypted. There have been no changes from the encrypted model to the unencrypted one. Originally, all of our FET models were encrypted. Only recently have we updated all of our PSpice discrete FET and power block models to unencrypted ones.
    3. You can easily create a macro in TINA-TI of the unencrypted PSpice model using instructions: .
    4. Both models should work for AC and/or transient simulations.
    5. Yes, capacitances are modeled.
    6. Yes, charges are modeled.

    Please feel free to contact me if you run into any problems. I will close this thread but you can always re-open by replying.

    Dear John,

    i downloaded this PSPICE model for your web page 

    SLPM119A.ZIP

    opened TINA-TI , go to Tools -> New Macro Wizard -> selected the CSD19534Q5A.lib file

    1) what i need to select from this drop down?  The last one csd19534q5a?

    2) does this 5 option csd19534q5a also includes the three upper selections ( cgs, cgd, cds)?

    3) now i selected the shape

    4)  is this right that 1 is drain, 2 is gate and 3 is source for this model? how can i check this?

    Best Regards.

    Hi David,

    To answer your questions:

    1. Yes, select the CSD19534Q5A subcircuit.
    2. Yes, the other subcircuits are included and instantiated in the FET subcircuit.
    3. Shape is good.
    4. Normally all of our FET models are as follows: 1=D  2=G  3=S.

    Let me know if you have any problems.
