[C] Under-Voltage Protection (P-side, UVDB)
a1. Control supply voltage rises : After the voltage level reachs UVDBr, the circuits start to operate when the next input is applied.
a2. Normal operation : IGBT ON and carrying current.
a3. Under-voltage trip (UVDBt).
a4. IGBT OFF inspite of control input condition (there is no FO signal output).
a5. Under-voltage reset (UVDBr).
a6. Normal operation : IGBT ON and carrying current.

Note : RC coupling at each input (parts shown dotted) may change depending on the
PWM control scheme used in the application and on the wiring impedance of
the application’s printed circuit board.
