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.

17)
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 4 and
circuit page 10).

In case of an inverse current of 3A the both status outputs must not be disturbed.
The neighbour channel can be switched normally; not all paramters lay within the range of the spec
Please note, that in case of an inverse current no protection function is active. The power dissipation is
higher compared to normal operation in forward mode due to the voltage drop across the drain-source diode
(as it is with reverse polaritiy). If this mode lasts for a too long time the device can be destroyed.
