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 3).
