OPERATION OF PROTECTION CIRCUIT

ADJUSTMENT OF OUTPUT FALL TIME

(1) In case the gate voltage is “H” and the collector voltage is high,(When the protection circuit is operating)this hybrid IC will recognize the circuit as short circuit andIn case you want to decrease the speed of reverse bias when theimmediately reduce the gate voltage. Besides, put out
protection circuit is operating, you can adjust that speed by connecting
error signal (”L”) which inform that protection circuit is operating
the capacitor (Cs) between pin 6 and 7.(Please refer to under figures. )at the same time from pin 8.
(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 (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 pin2 and 3.
(4) When the short circuit protection works, the soft gate shut down
circuit works to suppress collector surge voltage of IGBT.
Furthermore, when it is necessary to be more soft, by adding a capacitor toCs terminal, it is possible to make gate shut down speed more slow.

PRECAUTION(1) Voltage compensate capacitors are expected to be located as close aspossible from the hybrid IC.
(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 zener diode between
pin 6 and 1 is necessary like above diagram.
(4) In case pin 2 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 operating, please pin 2 are open.
(5) Minimize the area of closed circuit of gate circuit and input gate signal circuitso as not to be affected by induction noise.
(6) When the built in short-circuit protection circuit need not be used,
please connect resistance of 4.7k ohm between pin 1 and 3.
At that time, D1 and Dz1 are not require, and pin 8 are not necessary to be connected.

FOR SAFETY USINGGreat detail and careful attention are given to the production activity of Hics, such as the development, the quality of production, and in it’sreliability.

However the reliability of Hics depends not only on their own factors but also in their condition of usage. When handling Hics, please

note the following cautions.

CAUTIONS

PackingCarrying

6The materials used in packing Hics can only withstand normal external conditions.
When exposed to outside shocks, rain and certain environmental contaminators, the packing materials willdeteriorates. Please take care in handling.
1)
2)
3)
4)
5)

Don’t 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 electricalcharacteristics, risk of solder ability, and external damage may occur.
1) Devices must be stored where fluctuation of temperature and humidity is minimal, 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.

Extended storage

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, be sure to check that the exterior is free from flawand other damages.

Maximum ratings

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 sure of polarity in inserting
leads into the board holes, conforming to the external view for the terminal arrangement.
