Some recommendations would include: 1. The input signal voltage (pin 14) cannot exceed 5.25V. The internal dissipation caused by the resultant increase in input current could damage the input optocoupler. A current limiting resistor (R1) is used to help prevent this. The resistor value is calculated by the formula: R1 = VIN - 1.7V - 150X 16 mA 2. The gate wiring of the IGBT gate-emitter drive loop must be shorter than 1 meter. 3. Twisted pair wiring is recommended for the gate-emitter drive loop to minimize mutual induction. 4. Pins 3, 7, 9 and 10 (not shown in the connection diagram) of the IGD962 are only used for testing. They should not be used as a connection in any application circuit. 5. If a large voltage spike is generated at the IGBT collector, the value of the gate resistor (RG) should be increased. 6. Capacitors C2 and C3 should be mounted as close to the driver as possible. 7. The peak reverse voltage rating of D1 must be higher than the peak value of the IGBT collector voltage. 8. The voltage level at pin 1 could go “High” depending on the reverse recovery characteristics of D1. A 30V zener diode DZ1 is connected between pin 1 and Pin 6 to prevent any problems caused by this. 9. If CTRIP is used, it be mounted as close to the driver as possible. The distance between CTRIP and pins 4 & 2 should be less than 5 cm. 10. The traces (or wires) between the DC/DC and the driver circuit should be as short as possible.
