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 4.7kΩ between PIN9 and 13(D1and DZ1are not
required).
