From what I can gather, the required supply current is at most 1mA when using a 5V supply.
The datasheet spec states that when driving a theoretically infinite load, this is the current required for the device. Your supply should source at most 1mA.
I hope this answers your question.
Do you have a PSpice schematic or TINA simulation file that you can share on this thread? That way, I can simulate the type of response you are seeing.
From the picture of your schematic, I don't see where 5V_HV is coming from.
I know this is from the zener so can you share your zener circuit as well?
Thank you for clarifying. Do you have a simulation and/or a scope capture of the comparator inputs and outputs? I would also like to see the waveforms in your "5V_HV" circuit.
This will help me better understand the issue you are experiencing :)
you should heavily increase this 5k resistance in front of your 5V Zener diode, otherwise you barbecue the Zener diode :-)
Try 100k and put a 100n cap in parallel to the Zener diode.
And keep in mind that 830V is a very dangerous voltage !!
