Short-Circuit Protection (N-side only, with external shunt resistor and CR filter)
A1: Normal operation – IGBT turn on and conducting current.
A2: Short-circuit current detected (SC trigger).
A3: IGBT gate hard interrupted.
A4: IGBT turn off.
A5: FO output with a fixed pulse width (determined by the external capacitance CFO).
A6: Input “L” – IGBT off.
A7: Input “H” – IGBT on is blocked during the FO output period.
A8: IGBT stays in off state.

Under-Voltage Protection (N-side, UVD)
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: IGBT turn off regardless of the control input level.
B5: FO asserted during the period from minimum pulse width or until control supply recover to UVDr.
B6: Under-voltage reset (UVDr).
B7: Normal operation – IGBT turn on and conducting current.
