Hello, Shawn,
According to the input voltage/current range, you can check DRV8428E or DRV8426E.
Actually, DRV8428EEVM and DRV8426EEVM can support both "BDC" and "STEPPER" motor operation. Customers can check them as an example.

Kuramochi,
I just verify it on an DRV8426EEVM. When the VREF steps down, we can see the ripple control decay mode gives the fast decay.

Wang Li
