In case of a fault condition the DIAG
considered as an output pin by the device.
The fault conditions are:
- overtemperature on one or both high sides (for example
if a short to ground occurs as it could be the case
described in line 1 and 2 in the table below);
- short to battery condition on the output (saturation
Possible origins of fault conditions may be:

detection on high side A.

When a fault condition is detected, the user can know
