Definition of Adjustment 1) Adjustment of soft turn-off time:
(Operation of short circuit protection) When a desaturation is detected the hybrid gate driver performs a soft shutdown of the IGBT. The Soft turn-off time is 4.5uS. You can connect an Rf or Cf to adjust the Soft turn-off time. (Connecting Rf will increase the soft turn-off time and connecting Cf will decrease the soft turn-off time.) The soft turn-off time must be set 2.5uS< Tcf <10uS. Please refer to the below table.
tPHL
2) Adjustment of short-circuit detection time delay
(Operation of short circuit protection) The short-circuit detection time delay is defined between the time in which a desaturation is detected and the time in which the gate voltage fall down to 90% of extent. This diver have a minimum short-circuit detection time delay, and you can adjust the short-circuit detection time delay by connecting the capacitor (Ctrip) between PIN12 and 16. But the short-circuit detection time delay must be set less than 3.5uS. Please refer to below table.(the data only for refer)

Application Notes
1. The isolated DC/DC converter is only for the gate drive; 2. The IGBT gate-emitter drive loop wiring must be shorter than 1 meter; 3. The IGBT gate-emitter drive loop wiring should be twisted; 4. If large voltage spike is generated at the collector of the IGBT, the IGBT gate resistor should be increased; 5. The external capacitors or resistors should be set as close as possible to the Hybrid IC; 6. The voltage compensate capacitors should be low impedance and be located as close as possible to the Hybrid IC; 7. The peak reverse voltage of the diode D1(to connect PIN13) must be higher than the peak value of the IGBT collector voltage; 8. When recovery current flow in D1, PIN13 is applied high voltage. In the case, counterplan for protection which insert a zener diode between PIN10 and 13 are necessary like above diagram(DZ1);
9. When the built in short-circuit protection circuit need not be used, please connect resistance of 4.7k between PIN9 and 13(D1and DZ1are not
required).
