2) Supply voltages higher than Vbb(AZ) require an external current limit for the GND and status pins, e.g. with a
150 resistor in the GND connection and a 15 kresistor in series with the status pin. A resistor for the
protection of the input is integrated.
3) RI = internal resistance of the load dump test pulse generator
4) VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839
