11) 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 and Status currents have to be limited (see max. ratings page 3 and
circuit page 8).
12) External pull up resistor required for open load detection in off state.
