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.

To minimise power dissipation at reverse battery
operation, the overall current into the IN and IS pin
should be about 80mA. The current can be provided by
using a small signal diode D in parallel to the input
switch, by using a MOSFET input switch or by proper
adjusting the current through RIS.
Since the current via Rbb generates additional heat in
the device, this has to be taken into account in the
overall thermal consideration.

The device can be operated in inverse load current
mode (VOUT > 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
current operation is not possible!

This range for the current sense ratio refers to all
devices. The accuracy of the kILIS can be raised by
means of calibration the value of kILIS for every
single device.
