Some recommendations would include: isolated gate drive power at pin 8 (VCC, 15V) and pin 10 (VEE, -8V). These outputs share a common ground at pin 9. This allows the 1 The D200E is a 2W DC/DC converter. It will convert a 5, 12, or 24V bus IGD to provide a floating gate drive suitable for high or low side voltage to the 15V needed to power the IGD1208W. The SR7805 is a switching. Low impedance electrolytic capacitors (C6 and C7) are switching POL regulator. It provides a stable 5V input signal voltage used to decouple the internal supply outputs. It is important that to the input (pin 3) of the IGD1208W. these components be selected for low impedance and a maximum 2 The input signal voltage (pin 3) cannot exceed 5.25V. The internal allowable ripple current that is sufficinet for the application. Assuming dissipation caused by the resultant increase in input current could the ripple current in the decoupling capacitors is about equal to the damage the input optocoupler. A current limiting resistor (R1) is used rms gate current, it can be estimated by the formula: to help prevent this. The resistor value is calculated by the formula: 8 The voltage level at pin 13 could go “High” depending on the reverse recovery characteristics of D1. A 30V zener diode DZ1 is connected between pin 13 and pin 10 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 9 and pin 13 (D1 and DZ1 are not required with this configuration). 10 The IGD1208W has a short circuit detection time delay of 3.0 µS, sufficient for most applications. If required, this can be extended by connecting a resistor (RTRIP) between pin 16 and pin 12. Contact the factory for details. 11 To help limit any transient voltage surges that could occur when a short circuit is interrupted, a soft shutdown is provided by the tP x f IGD1208W.The default time is set to 4.5 µS, but it can be adjusted I V RMS = IP IN - 1.7V R1 = - 150X 3 from 2.5 µS to 10 µS by using either CF or RF.

The RC filter (C5 and R3) help provide noise immunity. If the short circuit protection circuit is not used, these components can be eliminated and pin 15 should be left open.
