Diagnosis  
9.2.2  
Fault Current (IIS(FAULT))  
As soon a protection event occurs, changing the value of the internal retry counter (see Chapter 8.3 for more  
details) from its reset state, a current IIS(FAULT) is provided by pin IS when DEN is set to “high”. The following 3  
situations may occur:  
If the channel is ON and the number of retries is lower than “nRETRY(CR) + nRETRY(CYC) * nRETRY(NT)”, the current  
IS(FAULT) is provided for a time tIS(FAULT)_D after the channel is allowed to restart, after which IIS = IL / kILIS (as  
I
shown in Figure 35). During a retry cycle (while timer tRETRY is running) the current IIS(FAULT) is provided each  
time the channel diagnosis is checked  
If the channel is ON and the number of retries is equal than “nRETRY(CR) + nRETRY(CYC) * nRETRY(NT)”, the current  
IIS(FAULT) is provided until the internal counter is reset (either by expiring of tDELAY(CR) time or by DEN pin  
pulse, as described in Chapter 8.3.1)  
If the channel is OFF and the internal counter is not in the reset state, the current IIS(FAULT) is provided each  
time the channel diagnosis is checked
