†
SY_FLT automatically resets after the SSD event is over, without requiring FLT_CLR to be asserted. 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.
