Under-Voltage Protection (N-side, UVD)

A1: Normal operation – IGBT turn on and conducting current.

A2: Short-circuit current detected (SC trigger).

A3: All N-side IGBT gate hard interrupted.

A4: All N-side IGBTs turn off.

A5: FO output with a fixed pulse width of tFO(min) = 20µs.

A6: Input “L” – IGBT off.

A7: Input “H” – IGBT off in spite of “H” input.

A8: Normal operation – IGBT on and conducting current.

B1: Control supply voltage rise – After the voltage level reaches UVDr, the drive circuit begins to work

at the rising edge of the next input signal.

B2 : Normal operation – IGBT turn on and conducting current.

B3: Under-voltage trip (UVDt).

B4: All N-side IGBTs turn off regardless of the control input level.

B5: FO output during under-voltage period, however, the minimum pulse width is 20µs.

B6: Under-voltage reset (UVDr).

B7: Normal operation – IGBT turn on and conducting current.
