(2) minimize the area of closed ci rcuit of gate circuit so as not to be affected by induction noise. (3) d1 requires approximately the same voltage of power modules. (4) when recovery current flow in d1 , pin 30 is applied high voltage . in that case , counterplan for protection which insert a zener diode between pin21 and 30 are necessary like above diagram. (5) when you make late speed of reverse bias at the time of short circ uit protection operation, please adjust and connect a capac itor between pin 21 and 27. (6) when the built in short-circuit prot ection circuit need not be used, please connect resistance of 4.7k ohm between pin 30 and 20.

(2) the protection circuit reset and resorted to ordinary condition if input sign is ?l? when the predetermined time(1 ~ 2ms) passed. (?l? period needs 15us or more ) (3) when the output rises, the controlled time detect short circuit (typ 2.8us) is set up so that on-time of igbt can be secured properly. it is possible to adjust that time by connecting the capacitor (ctrip) between pin 21,22 and 29. 0% 90% 50% t1 t2 10% vo input signal adjustment of output fall time (when the protection circuit is operating) in case you want to decrease the speed of reverse bias when the protection circuit is operating, y ou can adjust that speed by connecting the capacitor (cs) between pin 21 and 27.
