DRV8251: Slow decay, need fast decay with both inputs high.

Hi Experts,

Seeking your assistance on this query about DRV8251 from Cx:

I have been testing the DRV8251 as a replacement for the ST L6201 to drive a stepper motor. Everything was going great until it was noticed that the application vibration increased. Looks this the difference is most likely related to when both inputs are high, instead of fast decay (both top FET's are ON, both lower FET's are OFF) all FET's are OFF. 

Any ideas on what we could do?
