1)Short circuit is defined as a combination of remaining resistances and inductances. See schematic on page11.

2)VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839.

3)See also diagram on page 11.

4)See also on page 8. Slew rate limitation can be achieved by means of using a series resistor RIN in the input path. This resistor is also required for reverse operation. See also page 10.

10)For operation at voltages higher then |16V| please see required schematic on page 10.

11)Permanent Inverse operation results eventually in a current flow via the intrinsic diode of the power DMOS. In this case the device switches on with a time delay td(inv)) after the transition from inverse to forward mode.
