(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 22 is applied high voltage . in that case , counterplan for protecti on which insert a zener diode between pin 22 and 16 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 c apacitor between pin 16 and 18. v i v o t phl t plh t r t f 50% 10% 90% 90% v i 0v v o 0v -5v t tri p 1 , 2 t time r pin 20 output 10v 0v 6 7 22 13 c1 17 r g VLA551K-01R 18 4.7k 16 20 1 2 3 4 3.3k 14 21 c2 c3 ctrip cs dz1 dz2 dz3 hc04 etc. v in =5v 15 d1 v in

(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 2.7us) 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 16 and 21. 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, you can adjust that speed by connecting the capacitor (cs) between pin 16 and 18.
