DRV8412: VDD capacitor calculation

Part Number: DRV8412

Hi

Is there a way to calculate the minimum VDD capacitor in a stepper and BLDC motor control system?

Are there a difference in these calculation for driving a stepper or a BLDC?

Are there any suggestion how to find the smallest capacitor value for a drive system? I could I measure if the choosen capacitor is to small?

Thanks for you answer in advance an kind regards
