MCF8315C: DRV10987

Tool/software:

Hello

I have a question about MCF8315C TSSOP product.

This product's package type is same as the DRV10987 and has same package size.

But their thermal resistances are very different.

Rather MCF8315C TSSOP's thermal resistances are similar with MCF8315C QFN type.

So I want to know why MCF8315C and DRV10987 have different thermal resistnaces.

Thank you.
