DRV8832: 10V overshoot


we are using DRV8832 and observe 10V overshoots when the VSET (coming from an external DAC) changes quickly over time.

Supply is 5V.

We have a SW patch to change it slowly, but I wanted to ask if there is a workaround (I dread no, as should be the back-EMF of the brushed motor).

Unfortunately I have no scopeplot to confirm it is not RF coupled noise (the 10V overshoot should have destroyed the part).

Fact is that it is observed when VSET quickly change.

Any advice (in the meantime I will try to gather some scopeplot)?

thanks a lot in advance
