TLV840: Request for PSpice Model for TLV840NADL20DBVR Device

JUAN IGNACIO LOPEZ MUDARRA
Prodigy 10 points
Part Number: TLV840

Tool/software:

Hello TI Team,

I’m currently working on a design that uses the TLV840NADL20DBVR device, and I would like to simulate its behavior in PSpice for TI. However, I haven’t been able to find the corresponding SPICE model in the official library or within the component search in the software.

Would it be possible to add the TLV840NADL20DBVR model to the PSpice for TI library? This would greatly facilitate the validation and simulation process for those of us integrating this component into our designs.

Thank you in advance for your attention. I look forward to any updates or alternatives you may offer.

Best regards,
Juan Ignacio López

    Hi Juan,

    The threshold values can be modified in the TLV840 PSpice model. To do this, you can download the original model from ti.com: TLV840 PSpice Model. Once you've downloaded this model, open it up make a copy of the "tlv840madl13_trans.lib" file, and name it "tlv840madl20_trans.lib". Open this file in a text editor and change vitp to 2.1 and vitn to 2.0, as shown here:

    You can also replace any mention of "TLV840MADL13" to "TLV840MADL20" in the file to prevent any confusion. From here, you can import the new .lib file into PSpice.

    Leaving the MR and CT pins disconnected will make the device behave the same as the N variant.
