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

Note:
1) RC coupling at each input (parts shown dotted) might change depending on the PWM control scheme used in the application and the wiring impedance of the application’s
printed circuit board. The input signal section of the Motion SPM 45 product integrates 5 kW (typ.) pull - down resistor. Therefore, when using an external filtering resistor,
please pay attention to the signal voltage drop at input terminal.
2) The logic input is compatible with standard CMOS outputs.
