DRV8842: Eagle/Fusion360 Design files DRV8842

This is the Error Message. The error is in line 104, gap 102.

Hi Fabian,

I'm not sure what the error message is. I am not familiar with the EAGLE software.

Can you try installing the Altium version and importing it to Autodesk Eagle?

HI Pablo,

Yes i tried different library versions. Can't use any of them.

Fabian,

I'm not quite sure what the error message is saying. I don't have EAGLE installed on my PC so I can't troubleshoot from my side. 

I tried downloading the Altium model and importing to Altium Designer yesterday but had no problems. Have you tried it on Altium?

Hi Pablo,

I'm using the Fusion360 Version of Autodesk. I tried to import different files via libraryio.

this guy has the same problem, i tried it the way in the comments, but it doesnt work.

Fabian,

Can you try importing another IC. Let's say the DRV8876. I want to understand if this issue is isolated to the DRV8842.

If you don't have any issues with the DRV8876, then I'll have to talk with our CAD modeling team to help fix the problem.

Hello Pablo,

I just tried as you said. Tried the DRV8871 and the 8876. It worked well with both, the "old" Eagle and the Fusion360.

thank you.

 Hi Fabian,

Thanks for valuable information.

This points to an issue with the DRV8842 model. I will work with our CAD modeling team to fix this model. This might take a while so I will reach out to you within a week with an update.

In the mean time, I recommend using the DRV8426PWPR model for your design. Even though the pinout is different, the footprint and package are the same as the DRV8842. Just map the DRV8842 pinout to the DRV8426PWPR. This will allow you to continue your design while we find a fix to the DRV8842 model.

Apologies for this inconvinience and appreciate your patience as we solve this problem.

Thank you! Have a nice weekend!

Hi Pablo,

Do you know if your CAD modeling team fixed the model of the DRV8842?

Thank you.

Hi Fabian,

I have not heard back from them. In the meantime, I download the model from out Altium library. https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/38/Integrated_5F00_Library-_2D00_-15.02.22-_2D00_-11.38.IntLib

Can you try downloading and exporting it to EAGLE.

Hi Pablo,

Thank for the idea to import the altium library. It seems to work!
But can you tell me just if the footprint is correct the way it is shown. I'm confused abot the green pad, and was thinking if it should be arranged vertical and not horizontal.

Thank you very much

Fabian,

I'm not really sure what the green area is. Have you tried to place it on your PCB design? The red vertical thermal PAD seems to be correct. One other thing I recommend is adding thermal vias on the PAD in case they are not present on the footprint model already.
