Supply voltages higher than Vbb(AZ) require an external current limit for the GND pin, e.g. with a 150 Ω
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

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.

connection. PCB is vertical without blown air.
13) Requires 150 Ω 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).
