Fig. 5 TIMING CHARTS OF THE DIPIPM PROTECTIVE FUNCTIONS
[A] Short-Circuit Protection (N-side only with the external sense resistor and RC filter)
a1. Normal operation: IGBT ON and outputs current.
a2. Short circuit current detection (SC trigger) (It is recommended to set RC time constant 1.5~2.0 μ s so that IGBT shut down within 2.0 μ s when SC.)
a3. All N-side IGBT's gates are hard interrupted.
a4. All N-side IGBTs turn OFF.
a5. F O outputs with a fixed pulse width determined by the external capacitor C FO .
a6. Input = “L”: IGBT OFF
a7. Fo finishes output, but IGBTs don't turn on until inputting next ON signal (L H).
(IGBT of each phase can return to normal state by inputting ON signal to each phase.)
a8. Normal operation: IGBT ON and outputs current.

[B] Under-Voltage Protection (N-side, UV D )
b1. Control supply voltage V D exceeds under voltage reset level (UV Dr ), but IGBT turns ON when inputting next ON signal (L H).
(IGBT of each phase can return to normal state by inputting ON signal to each phase.)
b2. Normal operation: IGBT ON and outputs current.
b3. V D level drops to under voltage trip level. (UV Dt ).
b4. All N-side IGBTs turn OFF in spite of control input condition.
b5. Fo outputs for the period determined by the capacitance C FO, but output is extended during V D keeps below UV Dr .
b6. V D level reaches UV Dr .
b7. Normal operation: IGBT ON and outputs current.
