3) Not shorting all outputs will considerably increase the on-state resistance, reduce the peak current capability
and decrease the current sense accuracy
4) Otherwise add up to 0.7 mΩ (depending on used length of the pin) to the RON if the pin is used instead of the
tab.
5) RI = internal resistance of the load dump test pulse generator.
6) VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839.
