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. RI = internal resistance of the load dump test pulse generator VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839

Add IST, if IST > 0, add IIN, if VIN>5.5 V Integrated protection functions are designed to prevent IC destruction under fault conditions described in the data sheet. Fault conditions are considered as "outside" normal operating range. Protection functions are not designed for continuous repetitive operation. 9) Short circuit current limit for max. duration of td(SC) max=450 s, prior to shutdown 10) Requires 150 resistor in GND connection. The reverse load current through the intrinsic drain-source diode has to be limited by the connected load. Note that the power dissipation is higher compared to normal operating conditions due to the voltage drop across the intrinsic drain-source diode. The temperature protection is not active during reverse current operation! Input and Status currents have to be limited (see max. ratings page 2 and circuit page 7).
