Fig. 5 TIMING CHARTS OF THE DIP-IPM PROTECTIVE FUNCTIONS
[A] Short-Circuit Protection (N-side only)
(For the external shunt resistor and CR connection.)
a1. Normal operation : IGBT ON and carrying current.
a2. Short circuit current detection (SC trigger).
a3. Hard IGBT gate interrupt.
a4. IGBT turns OFF.
a5. FO timer operation starts : The pulse width of the FO signal is set by the external capacitor CFO.
a6. Input “H” : IGBT OFF state.
a7. Input “L” : IGBT ON state.
a8. IGBT OFF state.
[B] Under-Voltage Protection (N-side, UVD)
a1. Normal operation : IGBT ON and carrying current.
a2. Under voltage trip (UVDt).
a3. IGBT OFF in spite of control input condition.
a4. FO timer operation starts.
a5. Under voltage reset (UVDr).
a6. Normal operation : IGBT ON and carrying current.
