When short circuit occurs, the voltage V
switched-off. The fault is reported to the isolated side of the driver as long as the active level of PWM signal
is applied (see Figure 8). It is absolutely necessary that after failure reporting the PWM generator will not
send PWM pulses in time intervals shorter than 50ms, make sure that the junction temperature does not rise
above 150°C otherwise the module might be destroyed. The /FAULT signal has a negative logic but can be
changed to positive logic during the assembly process or after a modification. To change the logic to positive
logic the SN74LVC1G97DCKR (IC
