But even if there was such a limit, it wouldn't matter as max VID is 1.6V.
And I don't even see the point such 2.0V limit as the offset voltage trigger (VID+175mV) will always cause OVP event before the 2.0V trigger.
IOUT - IOUT has the same output as IDROOP with
additional OCP adjustment function. In actual application, a
resistor needs to be placed between IOUT and GND to
ensure the proper operation. The voltage at IOUT pin will be
proportional to the load current. If the voltage is higher than
2V, ISL6327 will go into the OCP mode, this means it will
shut down first and then hiccup. The additional OCP trip
level can be adjusted by changing the resistor value

It's a form of OCP based OVP.
