Maximum Vcc voltage with short circuit protection
The maximum Vcc voltage with short circuit is the maximum voltage for which the part is able to protect itself under test
conditions representative of the application. 2 kind of short circuits are considered : terminal and load short circuit.

Maximum current during reverse circulation
In case of short circuit to battery, a voltage drop of the Vcc may create a current which circulate in reverse mode. When
the device is on, this reverse circulation current will not trigger the internal fault latch. This immunization is also true when
the part turns on while a reverse current flows into the device. The maximum current (I rev) is specified in the maximum
rating section.
