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.

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.
