drain connection. PCB is vertical without blown air. (see page 18)
Not subject to production test, specified by design
VLoadDump is set up without the DUT connected to the generator per ISO 7637-1 and DIN 40839. Supply
voltages higher than Vbb(AZ) require an external current limit for the GND pin, e.g. with a 150 Ω resistor in
GND connection. A resistor for the protection of the input is integrated.

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.

Requires a 150 Ω resistor in GND connection. The reverse load current through the intrinsic drain-source
diode has to be limited by the connected load. Power dissipation is higher compared to normal operating
conditions due to the voltage drop across the drain-source diode. The temperature protection is not active
during reverse current operation! Input current has to be limited (see max. ratings page 6).
