The DRV8874 datasheet states: "The internal blanking time helps to prevent voltage and current transients during output switching from effecting the current regulation. These transients may be caused by a capacitor inside the motor or on the connections to the motor terminals. The internal deglitch time ensures that transient conditions do not prematurely trigger the current regulation. In certain cases where the transient conditions are longer than the deglitch time, placing a 10-nF capacitor on the IPROPI pin, close to the DRV887x, will help filter the transients on IPROPI output so current regulation does not prematurely trigger. The capacitor value can be adjusted as needed, however large capacitor values may slow down the response time of the current regulation circuitry." (emphasis added).
I'm noticing spikes on IPROPI when the output transitions between on/off: (red is IPROPI pin and blue is the VM)
Is this indicative of where the use of a capacitor on the IPROPI pin would be suggested?
