Connection Notes: To minimize the potential for problems (and/or failures) caused by induced noise, EMI interfer- ence and/or oscillation, the connection of the gate driver must be done with great care. Some recommendations would include: 1. The input signal voltage (pin 14) cannot ex- ceed 5.25V. The internal dissipation caused by the resultant increase in input current could damage the input optocoupler. A current limit- ing resistor (R 1) is used to help prevent this. The resistor value is calculated by the formula: . 150R mA VV IN X= - - 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 4, 7, 8, 10 and 11 (not shown in the connection diagram) of the IGD841 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 G) should be increased. 6. Smoothing capacitors C 2 and C3 should be mounted as close to the driver as possible. 7. An internal circuit sets up a -5V off-gate voltage at pin 9 to protect against faults in the off state. Do not apply an external voltage to pin 1. 8. The peak reverse voltage rating of D 1 must be higher than the peak value of the IGBT collector voltage. 9. The traces (or wires) between the power source (V CC) and the driver circuit should be as short as possible.
