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 k resistor 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
