Short circuit is defined as a combination of remaining resistances and inductances. See schematic on
page11.
VLoad dump is setup without the DUT connected to the generator per ISO 7637-1 and DIN 40839.
See also diagram on page 11.
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.

Provide a current path with load current capability by
using a diode, a Z-diode, or a varistor. (VZL+VD Vbb > 0V). The current sense feature is
not available during this kind of operation (IIS = 0). In
case of inverse operation the intrinsic drain source
diode is eventually conducting resulting in considerably
increased power dissipation.
The transition from inverse to forward mode can result
in a delayed switch on.
Note: Temperature protection during inverse load
