CIRCUIT STATE
b1: Control supply voltage V D rises – After V D level reaches under voltage reset level (UV Dr ), the circuits
b2 : Normal operation – IGBT turns on and carries current.
b3: V D level dips to under voltage trip level (UV Dt ).
b4: All N-side IGBT’s turn off in spite of control input condition.
b5: F O is low for a minimum period determined by the capacitance C FO but continuously during UV period.
b6: V D level reaches UV Dr .
b7: Normal operation – IGBT turns on and carries current.
CIRCUIT STATE
PROTECTION
VOLTAGE V D
a1: Normal operation – IGBT turns on and carries current.
a2: Short circuit current is detected (SC trigger).
a3: All N-side IGBT's gate are hard interrupted.
a4: All N-side IGBT's turn off.
a5: F O output wirh a fixed pulse width (determined by the external capacitance C FO ).
a6: Input "L" – IGBT off.
a7: Input "H" – IGBT on, but during the F O output perid the IGBT will not turn on.
a8: IGBT turns on when L→H signal is input after F O is reset.
