c1 : Normal operation: IGBT ON and carrying current.
c2 : Over current detection (OC trigger).
c3 : Hard IGBT gate interrupt.
c4 : IGBT turns OFF.
c5 : Fault output timer operation starts.
c6 : Input “L” : IGBT OFF state.
c7 : Input “H”: IGBT ON state, but during the active period of
fault output the IGBT doesn’t turn ON.
