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.

a short circuit is interrupted, a soft shutdown is provided by the
