Cannot able to run the spice model for allegro current sense

[Arunsarma]

I cannot able to run the allegro current sense whole spice file is attached. Which is perfectly working in LTSpice
I think the issue related to universal operational amplifier library.

Hi Arunsarma,

You can run it, but it requires some tedious modifications to the model listings.

The followings are what I did.

1. In ASC732_3.lib, change the A1 device to a ¥1 device and add a 3.3V voltage source.
   

2. In ASC732_3.lib, change the model name from level.2 to level2.
   

   

3. In UniversalOpAmp2.lib, copy all the level.2 models, create a new file named level2.lib, paste them, and rename level.2 to level2 in its list.
   'UniversalOpAmp2.lib’ can be found in your LTSpice installation folder, for example, LTspice\lib\sub.
   Copy all the lines from .subckt level.2 to .ends level.2.

4. In level2.lib, change the A1 device to an Ã1 device and add a voltage source.
   

   

5. In level2.lib, change .model Q SW … to .model Q SW ( Ron=10 Roff=10Meg Vt=0 Vh=-.1 ).

Hi @EL34

Thanks a lot for your support. The model is working Perfectly
