To avoid FLT_CLR conflicting with the SSD sequence of operations, in the event of a SSD during normal operation it is recommended not to apply FLT_CLR while SY_FLT is active. At power supply start-up instead, it is recommended to keep FLT_CLR active to prevent spurious diagnostic signals being generated, as described in section 1.1 Start-Up Sequence and in section 1.4.5 Fault Management at Start-up. †† Holding FLT_CLR high all time will not allow the gate driver to latch the FAULT status and migth compromise power system protection. |
