Got it.

Amended to....

... any voltage above 1.67v, longer in time than deemed prudent by Papa, will trip the output protection.

I am curious. Assuming infinitely stiff power rails, during the grace period, is the current limited only by the impedance of the load + the impedance of the drain sense resistors + MOSFET Rdson?

It looks sissy enough for me.

Good one. That made me chuckle. Its funny and at the same time a very good point.

When I lashed up my hockey puck OPS, I measured some of the wires on a good DMM to make sure I was not wiring up the circuit with pieces that were significantly more resistance then the RDSon of the hockey pucks. For the n-channel part that I used, the RDSon is less than one milliohm and wires become a significant factor for high current transients.

When I make a more permanent version, I will use the fattest wire that will fit into the ring terminal and then characterize each wire.
