So, recently i have been trying to import IR2110 driver IC for simulation, i found this PSPICE model from the infineon website, i did the following steps, i) open the .lib file of the component in LTspice ii) click on .SUBCKT and "create symbol" option but when i get all the connections right, i get this below error, i tried googling for this error, but by far there has been no straightforward answer. I get that this error is due to undefined number of pins on the symbol and the .lib file, but i check the .lib file and compared, and there were no mismatch in the number of pins, the symbol still has 11 pins, as it was generated from the software itself, using the library. Looking forward for help. Thank you.

 

Hi CR,
Please post your asc file and model.

Sorry for this rookie error, i have edit the file into the post, please look into it.

IDK why, but my post has been flagged "solved", why did this happen.?

 

Hi CR,
I misunderstood, I thought you had found the problem.

Hi RJ,
Downloaded your files, can you post an image of the circuit without the error label?
E

My Model on the Left is a different pinout to yours on the right.

Hi CR,
This zip is a copy of my IR2110 files.
Give it a try.

the given component runs without errors, but still I'm about to test this with the final circuit, ill get back to you in morning, thank you for your help mate.

So, i tried this component and i get the desired output for the LOW side, but the same doesn't work for HIGH side, even with external bootstrap capacitors, i wanted to check the outputs before connecting the MOSFET's on the output stage. for some reason, the output of HIGH side remains at constant voltage, also the output of the HO and LO, should be 5v as we set in the circuit, but it swings from 0-11v, so can there be any error while importing the component, or is there something wrong with my simulation. I'm following the circuit from great scott's class D amplifier design, below is the schematic. simulation file and I'm using the new component library you provided.

 

hi Cr,
I think you have posted the wrong asc file, its the old version?

I have made changes to the old file itself, you can see the new name of the component "IR2110_" in the schematic. It's still the same file, but with new component.

 

HI,
This is what I see when opening your last asc file, it is not the same as the file as the circuit you posted

Class D audio amp.?

That's the circuit i intend to follow, but first i wanted to check the outputs of the HO and LO output waveforms before connecting. the circuit is this below. The file is correct.

 

Hi,
That model will not run as expected, I will tag @Bordodynov who created the model, he may be able to help.

E
BTW: please do not modify the model asy files, it means I have to modify mine to suit.

Can you provide me the spice model you used above, and also how to include it properly, it seems like I'm missing something here, i get the desired output for lowside but fails at high side.

 

Chethan_Raj
upload your asc file and LM2901. I will make the necessary adjustments.

Here you go.... these are the Infineon ones.
