DRV8343-Q1: simulate DRV8343-q1 on PSpice program

Juanjo Solano Moreno

Part Number: DRV8343-Q1

Tool/software:

Hi, I would like to simulate the BLDC motor driver DRV8343-q1 on your PSpice program. Is there any chance to do that? Even if we buy this product?

Thanks.

Hi Juan,

Here is the Pspice file:

slvmd44.zip

Let me know if you have trouble accessing it

Regards,

Yara

Hi, I found it, but the DVDD pin is not working as it should.

I'll send you a photo of the error.

Hi Juan

is DVDD connected to a power source?

if so, have you tried explicitly defining DVDD in your circuit to see if that helps?

Regards,

Yara

Hi Yara, no, it is connected to a capacitor that is connected to GND, as it is connected in the datasheet. I'm sharing a folder with the project on Google Drive.

Best regards,

Juan

Hi Juan,

I can not access google drive on TI network. Just want to double check you are using PSpice correct? not another simulation tool?

I'm not familiar with the model, I will try and see if we have any resources that could help.

Regards,

Yara

Hi Yara, yes, I'm using the PSpice model you have at TI. Anyway, I'll buy it and try it out at the University.

Regards and thanks for the support,

Juan
