) 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 2 and circuit page 7).
