Hi team,

Customer is requesting PSpice model for DRV8872-Q1 (DRV8872DDARQ1). Please let me know how to support this.

By the way, DRV8876-Q1 PSpice model is linked to the product folder of DRV8872-Q1 - I suppose this is a mistake?

PY,

This is not a mistake. The DRV8876-Q1 model is the closest we have to a behavioral model for the DRV8872-Q1. That is the best we can offer at this time.

Regards,

Ryan

Hi Ryan,

Thanks. So question is can customer use DRV8876-Q1 model to simulate DRV8872-Q1? They still look different...

PY,

That is the best we can offer. Yes, they are different, but the interfaces are the same from a logic standpoint. DRV8876-Q1 adds ipropi output that can be ignored in the model.

Ryan
