Supply voltages higher than Vbb(AZ) require an external current limit for the GND pin, e.g. with a 150 resistor in the GND connection. 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 EAS is the maximum inductive switch off energy Device on 50mm*50mm*1.5mm epoxy PCB FR4 with 6cm2 (one layer, 70m thick) copper area for Vbb connection.

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. 11) not subject to production test, specified by design 12) Device on 50mm*50mm*1.5mm epoxy PCB FR4 with 6cm2 (one layer, 70m thick) copper area for V bb connection. PCB is vertical without blown air. 13) 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 1 and circuit page 7).

For inductive load currents up to the limits defined by ZL (max. ratings and diagram on page 8) each switch is protected against loss of Vbb. Consider at your PCB layout that in the case of Vbb disconnection with energized inductive load all the load current flows through the GND connection.
