BTS vs BTN 7960/7970: Is there a difference

Hey y’all

I’m currently working on a project which involves the use of two BTS 7960 motor drivers. I’ve been following a circuit diagram which I’ve attached, but I’ve only just noticed that the diagram I’ve been referring to is one for a BTN 7970.

I’ve compared this diagram to another and they both look very similar, but I’ve failed to find anyone else talking about these two chips and if they’re identical or not.

Could any of you guys help me out? Maybe point me in the right direction for this question?

Thanks.

I'm not sure about the BTS/BTN difference, but the brochure for them has a comparison table: https://www.mouser.co.uk/pdfdocs/NovalithIC_Brochure_Aug08.PDF
