GREATER THAN V SC AT THE END OF THE T TRIP DELAY THE DRIVER
WILL ERRONEOUSLY INDICATE THAT A SHORT CIRCUIT HAS OCCURRED.
TO AVOID THIS CONDITION THE VLA502-01 HAS PROVISIONS FOR
EXTENDING THE T TRIP DELAY BY CONNECTING A CAPACITOR (C TRIP )
BETWEEN PIN 29 AND V EE (PINS 21 AND 22). A CURVE
SHOWING THE EFFECT OF ADDING C TRIP ON TIME IS GIVEN IN THE
CHARACTERISTIC DATA SECTION OF THIS DATA SHEET. THE WAVE-
FORM DE?NING TRIP TIME (T TRIP ) IS SHOWN IN FIGURE 3. IF T TRIP
IS EXTENDED CARE MUST BE EXERCISED NOT TO EXCEED THE
SHORT-CIRCUIT WITHSTANDING CAPABILITY OF THE IGBT MODULE.
ADJUSTMENT OF SOFT SHUTDOWN SPEED
AS NOTED ABOVE THE VLA502-01 PROVIDES A SOFT TURN-OFF
WHEN A SHORT CIRCUIT IS DETECTED IN ORDER TO HELP LIMIT THE
TRANSIENT VOLTAGE SURGE THAT OCCURS WHEN LARGE SHORT
CIRCUIT CURRENTS ARE INTERRUPTED. THE DEFAULT SHUTDOWN
SPEED WILL WORK FOR MOST APPLICATIONS SO ADJUSTMENT IS
USUALLY NOT NECESSARY. IN THIS CASE C S CAN BE OMITTED.
IN SOME APPLICATIONS USING LARGE MODULES OR PARALLEL
CONNECTED DEVICES IT MAY BE HELPFUL TO MAKE THE SHUT-
DOWN EVEN SOFTER. THIS CAN BE ACCOMPLISHED BY
CONNECTING A CAPACITOR (C S ) AT PIN 27. A CURVE SHOWING
THE EFFECT OF C S ON SHORT CIRCUIT FALL TIME (T 1 , T 2 ) IS GIVEN
IN THE CHARACTERISTIC DATA SECTION OF THIS DATA SHEET. THE
WAVEFORM DE?NING THE FALL TIME CHARACTERISTICS IS SHOWN
IN FIGURE 3.
