1Integrated _{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 .

3Requires _{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).
