(2) D1,2 require approximately the same voltage of IGBT modules.
(3) In case pin 22 or 32 are operating, the Ctrip is expected to be wired as close as possible from pin. (Less than 5cm coming and going)In case of not using, please keep pin 22 or 32 open.
(4) Minimize the area of closed circuit of gate circuit and input gate signal circuit so as not to be affected by induction noise.
(5) When the built in short-circuit protection circuit need not be used, please connect resistance of 4.7k(1/4W) between
pin 23 and 21 (pin 33 and 31). At that time, D1 (D2) is not require.
(6) Please keep pin24 and 34 open ordinarily. These pins are exclusive to our specific product.
(7) About the IC which drives gate signal on input side, it is not recommended to use the one whose output is open collector oropen drain type.

OPERATION OF PROTECTION CIRCUIT(1) In case the gate voltage is “H” and the collector voltage is high, this hybrid IC will recognize the circuit as shortcircuit and immediately reduce the gate voltage. Besides, put out fault signal (”L”) which inform that protection
circuit is operating at the same time from pin 1 or 11.
(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 masked time detect short circuit (ttrip) 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 pin22 and 21 (32 and 31).
(If needed Ctrip, lough guide is 33~75pF)

LATCH & TIMER RESET SYSTEM IN SHORTCIRCUIT PROTECTION CIRCUITOPERATION FLOW ON DETECTING SHORT CIRCUITOnce the short-circuit protection circuit starts, it shuts down
the gate output and keeps alarm output, causing the latch
status. This status is canceled if the input signal is OFF when
specific time elapses after the activation of the short-circuit
protection circuit. Then, gate output depending on input
signals becomes possible. If the input signal is ON when
specific time elapses, the latch status is not canceled: it iscanceled when the signal becomes OFF.
As mentioned above, on the latch & timer reset system, thelatch status is resulted after activation of the protection circuitand shutdown of the gate output. Therefore, during thisperiod, gate output is not made no matter how much input
signals are received. For this reason, it is possible to safely
stop the entire equipment by sending error signals to themicrocomputer during this period to stop all gate signals.

VLA597-01R
DRIVER FOR IGBT MODULESFOR SAFETY USINGGreat detail and careful attention are given to the production activity of Hics, such as the development, the quality ofproduction, and in itʼs reliability. However the reliability of Hics depends not only on their own factors but also intheir condition of usage. When handling Hics, please note the following cautions.

CAUTIONS
PackingCarrying

The materials used in packing Hics can only withstand normal external conditions.
When exposed to outside shocks, rain and certain environmental contaminators, thepacking materials will deteriorates. Please take care in handling.
1)
2)
3)
4)
5)

Donʼt stack boxes too high. Avoid placing heavy materials on boxes.
Boxes must be positioned correctly during transportation to avoid breakage.
Don't throw or drop boxes.
Keep boxes dry. Avoid rain or snow.
Minimal vibration and shock during transportation is desirable.

Storage

When storing Hics, please observe the following notices or possible deterioration of
their electrical characteristics, risk of solder ability, and external damage may occur.
1)
Devices must be stored where fluctuation of temperature and humidity isminimal, and must not be exposed to direct sunlight. Store at the normal
temperature of 5 to 30 degrees Celsius with humidity at 40 to 60%.
2)
Avoid locations where corrosive gasses are generated or where much dust
accumulates.
3)
Storage cases must be static proof.
4)
Avoid putting weight on boxes.

Extendedstorage

When extended storage is necessary, Hics must be kept non-processed. When using
Hics which have been stored for more than one year or under severe conditions, besure to check that the exterior is free from flaw and other damages.

Maximumratings

To prevent any electrical damages, use Hics within the maximum ratings. The
temperature, current, voltage, etc. must not exceed these conditions.

Polarity

To protect Hics from destruction and deterioration due to wrong insertion, make sureof polarity in inserting leads into the board holes, conforming to the external view for
the terminal arrangement.
