When a short circuit occurs, the voltage U
and the IGBT is switched off. The fault is reported to the primary side of the driver as long as there is no
reset signal applied to the driver. The /FAULT signal is active low, the according schematic can be seen in
Figure 11.

Figure 12
The fault signal will be in low state in case of a short circuit until /RST is pulled down.
