Hi Team,
The customer made the design with reference to the datasheet. The motor current decreasing slope is about 0.87A/ms. If it is necessary to reduce the slope to 0.15A/ms, is it feasible? How to modify the configuration?

Annie

Annie,
There is no way to adjust the slew rate (output rise/fall time) on the DRV8874 itself.
However, we do have an automotive variant with edges approximately 3x slower.

Perhaps customer can consider this variant.
