Mr. Duncan,
I'll make sure to also capture GVDD, AVDD, DVDD and PVDD along with the nFault pin. Do you have a recommendation for the size of the ceramic capacitor on PVDD? I do have a 470uF electrolytic capacitor at the leads of where the power supply connects to the circuit.
I have access to a non-invasive current probe but I'm not sure that it'll be able to capture any spikes if there are any. I can also put a DMM in-line. To read the currents, I've just been using the lab power supply as it has a current readout although not a terribly precise measurement.
Also, I'll make sure to connect the current sense inputs to GND. Will the outputs be okay if just left open or should they be tied to GND as well?
Thank you for your help.
