Some recommendations would include: isolated gate drive power at pin 9 (VCC, 15V) and pin 7 (VEE, -8V). These outputs share a common ground at pin 8. This allows the IGD 1 The D200E is a 2W DC/DC converter. It will convert a 5, 12, or 24V bus to provide a floating gate drive suitable for high or low side switching. voltage to the 12 or 15V needed to power the IGD1205W. The SR7805 Low impedance electrolytic capacitors (C6 and C7) are used to decouple is a switching POL regulator. It provides a stable 5V input signal voltage the internal supply outputs. It is important that these components be to the input (pin 14) of the IGD1205W. selected for low impedance and a maximum allowable ripple current 2 The input signal voltage (pin 14) cannot exceed 5.0V. The internal that is sufficinet for the application. Assuming the ripple current in the dissipation caused by the resultant increase in input current could decoupling capacitors is about equal to the rms gate current, it can damage the input optocoupler. A current limiting resistor (R1) is used be estimated by the formula: to help prevent this. The resistor value is calculated by the formula: 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⍀ should be connected between pin 4 and pin 8. 10 The IGD1205W has a short circuit detection time delay of 1.6 µS. Sufficient for most applications. If required, this can be extended by connecting a capacitor (CTRIP) 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 t P x f V 1 . 7 V to 10 µS by using either CF or RF.

If the short circuit protection circuit is not used, these components can be eliminated and pin 2 should be left open.
