(2) The protection circuit reset and resort to ordinary condition if input signal is OFF when the premised 1~2msec passed.( OFF period needs 10us or more ) (3) When the output rises, the controlled time detect short circuit (Typ 2.6us) 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 pin15 and 21. PRECAUTION (1) Voltage compensate capacitors are expected to be located as close as possible from the hybrid IC. (2) D1 requires approximately the same voltage of power modules. (3) If reverse recovery time of D1 is long, pin22 is applied high voltage. In that case, counterplan for protection which insert a zener diode between pin 15 and 22 is necessary like above diagram. (4) In case pin 21 is operating, the Ctrip is expected to be wired as close as possible from pin 15 and pin 21. (Less than 5cm coming and going) 14
