Connection Notes: To minimize the potential for problems (and/or failures) caused by induced noise, EMI interference and/or oscillation, the connection of the gate driver must be done with great care. Some recommendations would include: 1 The D200E is a 2W DC/DC converter. It will convert a 5, 12, or 24V bus voltage to the 12 or 15V needed to power the IGD1205W. The SR7805 is a switching POL regulator. It provides a stable 5V input signal voltage to the input (pin 14) of the IGD1205W. 2 The input signal voltage (pin 14) cannot exceed 5.0V. The internal dissipation caused by the resultant increase in input current could damage the input optocoupler. A current limiting resistor (R 1) is used to help prevent this. The resistor value is calculated by the formula: . 150R mA VV IN X= - -
3 The gate wiring of the IGBT gate-emitter drive loop must be shorter
than 1 meter.
4 Twisted pair wiring is recommended for the gate-emitter drive loop to
minimize mutual induction.
5 If a large voltage spike is generated at the IGBT collector, the value of
the gate resistor (RG) should be increased.
6 The IGD1205W includes an internal DC/DC converter that provides
isolated gate drive power at pin 9 (V CC, 15V) and pin 7 (V EE, -8V). These outputs share a common ground at pin 8. This allows the IGD to provide a fl oating gate drive suitable for high or low side switching. Low impedance electrolytic capacitors (C 6 and C7) are used to decouple the internal supply outputs. It is important that these components be selected for low impedance and a maximum allowable ripple current that is suffi cinet for the application. Assuming the ripple current in the decoupling capacitors is about equal to the rms gate current, it can be estimated by the formula: xii tf RMS P P Where iP = peak current; tP = base width of pulse; and f = frequency. Capacitors C6 and C7 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 4 could go “High” depending on the reverse
recovery characteristics of D1. A 30V zener diode DZ1 is connected between pin 4 and pin 7 to prevent any problems caused by this. 9 If the short cicuit protection circuit is not used, a 4.7 k/H9024 should be connected between pin 4 and pin 8. 10 The IGD1205W has a short circuit detection time delay of 1.6 µS. Suffi cient for most applications. If required, this can be extended by connecting a capacitor (C TRIP) between pin 1 and pin 9. Contact the factory for details. If used, CTRIP should be mounted as close to the driver as possible.
11 To help limit any transient voltage surges that could occur when a shor
circuit is interrupted, a soft shutdown is provided by the IGD1205W. The default time is set to 4.5 µS, but it can be adjusted from 2.5 µS to 10 µS by using either CF or RF. Contact the factory for details.
12 If the IGD1205W short circuit protection is activated, it will immediately
shut down the gate drive and pull pin 2 low to indicate a fault (via OP 1). During normal operation, the collector of OP1 is pulled high by R2. In the event of a fault, the driver output is disabled and a fault signal is produced that lasts a minimum of 1 mS. The RC fi lter (C 5 and R3) help provide noise immunity. If the short circuit protection circuit is not used, these components can be eliminated and pin 2 should be left open.
