TINA/Spice/LP87524B-Q1: How to set Vout value at LP87524B-Q1 PSPICE simulation?

Tool/software: TINA-TI or Spice Models

Hello,

My customer would like to simulate LP87524B-Q1 using PSPICE model LP87524B-Q1_TRANS.LIB, but does not know how to set Vout.

At actual device, Vout can be set via I2V, but how can Vout be set in the simulation?

Best regards,

Hi Hirano-san,

My advise is to take a look for example testbench/schematic found from LP87524B tools/software folder.
In example testbench VOUT is set by using DC-voltage source.

Pspice model does not support voltage change with I2C.

Jari,

Thank you for your response.

I went to LP87524B tools/software folder, but I am not sure what you are exactly referring to.
Could do elaborate further, please?
What is the testbench/schematic I should take a look at?

Best regards,

K.Hirano

Hi Hirano-san,

The Pspice transient model includes Cadence project file which includes testbench.

Below screenshot about testbench.

Voltage change related DC-sources rounded with red color.
