Under-Voltage Protection (P-side, UVDB)

C1: Control supply voltage rises – After the voltage level reaches UVDBr, the drive circuit begins to work

at the rising edge of the next input signal.

C2: Normal operation – IGBT turn on and conducting current.

C3: Under-voltage trip (UVDBt).

C4: IGBT stays off regardless of the control input level, but there is no FO signal output.

C5: Under-voltage reset (UVDr).

C6: Normal operation – IGBT turn on and conducting current.

Over-Temperature Protection (N-side, OT)

D1: Normal operation – IGBT turn on and conducting current.

D2: LVIC temperature exceeds over-temperature tril level (OTt).

D3: All N-side IGBTs turn OFF iin spite of control input condition.

D4: FO outputs during over-temperature period, however, the minimum pulse width is 20µs.

D5: LVIC temperature is lower than over-temperature reset level.

D6: Circuits start to operate normally when next input is applied.
