TLV9022: Spice Model Inquiry

Art Mecina

Part Number: TLV9022
Other Parts Discussed in Thread: PSPICE-FOR-TI,

Hello,

I am not sure if this is the right forum to ask for this but the customer have downloaded the PSpice-For-TI simulation tool and placed a transistor (Q1breakN ) on his schematic. See below schematic. He right-clicked on the transistor and selected to see the PSpice model associated with it. He was surprised to see that the PSpice file tlv9022.lib opened. He did the same for TLV9022 and the same tlv9022.lib file opened. It seems as though TI have attached the wrong PSpice model file to Q1breakN.

Though when he tested the circuit with the QbreakN transistor, it actually works. This is in spite of the fact that the associated PSpice file is for the QbreakN transistor is the tlv9022.lib. I attach the Q1breakN.opj fileQbreakN.zip

He wanted to know how this happen and how it can be corrected?

Thanks in advance!

Hi Art,

We are in the process of uploading a new model for the TLV9022. I am not sure about the QbreakN... Thank you for attaching your PSpice file. I will take a look at that to see what is happening.

I will try to get back to you by the end of business 12/3.

Regards,

Joe

Hi Art,

We have a workaround for the issue while we are in the process of fixing this model collision.

If the schematic does not call for TLV9022 and only the QbreakN model, a workaround is to remove nom_pspti.lib from the sim profile or change it to “Add to Design”:

Now right-click the QbreakN part in the schematic and breakout.lib will be shown.

I hope this resolves the issue in the meantime.

Regards,

Joe

Thanks Joe!

Hope the model collision will be fixed soon.
