(2) d1 requires approximately the same voltage of power modules. (3) if reverse recovery time of d1 is long, pin1 is applied high voltage. in that case, counterplan for protection which insert a zener diode between pin 1 and 6 is necessary like above diagram. (4) in case pin 2 is operating, the ctrip is expected to be wired as close as possible fr om pin 2 and pin 4.

(2) 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 ti me by connecting the capacitor (ctrip) between pin2 and 4. (3) the protection circuit return to ordinary condition if input signal is off when the predetermined time(t_timer : 1~2ms) passed.
