The IC provides several protection features that
increase the SMPS system’s robustness and safety.
The following table shows the possible system failures
and the corresponding protection modes.

The VCC voltage is observed by comparator C13 if
20.5V is exceeded. The output of C13 is combined with
both the output of C3 which checks for V
the output of C4 which checks for V
