TVS1401: PSPICE Model Use

Darren (FAE)

Part Number: TVS1401

I'm trying to use Pspice for TI to model some behavior with the TVS1401 for an ADC.
(Basically trying to copy this: https://www.ti.com.cn/cn/lit/an/sbaa547/sbaa547.pdf)

Can somebody sent me a "PSPICE for TI" project file that is working so I can play around with resistor/cap values?

The model has an NC pin and I am getting errors (even if I set the pin as "No Connect" in the parameters page)

Regards,
Darren

Hi Darren,

Are you getting this error with the default simulation setup from the TVS1401 PSpice model? or in the circuit you're trying to implement?

Could you show me a screenshot of the error code or description?

Regards,

Sebastian

Sebastian,

PSPICE for TI doesn't have a default simulation setup; just the model.
I figured out how to solve the issue, but I still think a fix is needed.

Solution was from this forum; a post by "SteveG_in_MD"
https://www.pspice.com/error-ornet-1017-unconnected-pin-no-float-property

You have to manually open the model parameters in PSPICE for TI and add a parameter FLOAT then you have to call the NC pin a "UniqueNet".
I also clicked the checkbox for "No Connect" as well.

Doing this allows the model to function and simulations work.

Very strenuous, and it is the same for all the TVS1x ~ TVS3x models.

Darren

Hi Darren,

Thanks for bringing this to our attention, I'll look into having this fixed on our TVS PSpice models.
