CALCULATION FOR GATE DRIVE CURRENT (GATE AVERAGE CURRENT)
This product has isolated DCDC converter built in for gate drive.
The maximum output average current is 100mA per one channel.
This current means maximum gate average current.
When you decide the switching frequency,
please check the gate average current by next formula.

Idrive = (Q1＋lQ2l ) x f x N
 It must be less than 100mAIdrive: Gate average current
Q1: Gate charge at +15V (Read from data sheet of IGBT)Q2: Gate charge at -7V (Read from data sheet of IGBT)
f: Switching frequency of IGBT module
N: Parallel number of IGBT module

About the IC which drives gate signal on input side, it is not recommended to use the one whose output
is open collector or open drain type.
Note1) Gate Resistor is not installed at the time of shipment. Please solder the chosen resistor.
2) When you confirm the gate output without connecting IGBT, please invalidate the short-circuit protection function.
If connect resistance of 4.7k ohm between the C1(E1) and E1(E2) without main power supply,
the short circuit protection becomes invalid.
3) C5(6) is not installed at the time of shipment.
But if needed, please solder the chosen condenser.  (rough guide is 33~75pF, 50V, ceramic)
4) C14(15) is not installed at the time of shipment. Generally this is not be needed but a special case.
But if needed, please solder the chosen condenser.  (lough guide is 10~39pF, 50V, ceramic)5

OPERATION OF PROTECTION CIRCUITOPERATION FLOW ON DETECTING SHORT CIRCUIT(1) In case the gate voltage is “H” and the collector voltage is high,this drive unit will recognize the circuit as short circuit andreduce the gate voltage. Besides, put out fault signal (”L”) which
inform that protection circuit is operating at the same time fromFo terminal (9,13 pin of CN4).
(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 C5(C6)(If needed Ctrip, lough guide is 33~75pF)(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, it is possible to make gate shut
down speed more slow by adding capacitor C14(15).
(Generally no need but if needed, lough guide is 10~39pF)

TIMER
1~2ms
No

Yes

Once the short-circuit protection circuit starts, it shuts down thegate output and keeps alarm output, causing the latch status.
This status is canceled if the input signal is OFF when specific timeelapses 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 is canceled when the signal becomes OFF.

INPUT SIGNAL ISOFFNo

Yes

CLEAR ALARM
ENABLE OUTPUT

As mentioned above, on the latch & timer reset system, the latch
status is resulted after activation of the protection circuit andshutdown of the gate output. Therefore, during this period, 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 the microcomputer during this period tostop all gate signals.

THE WAY TO CALCULATE GATE RESISTANCE VALUE OF PARALLEL CONNECTION
RG_ON/1elem. = Gate ON resistance value per one element = Rb + (N x Rg_on)
RG_OFF/1elem. = Gate OFF resistance value per one element = Rb + (N x Rg_off)
Example of using adaptor unit VLA595-02R
Rb: 0.1Ω (Compound value of 4 chip resistors on VLA595-02R)
N: Parallel number of IGBT module

GAU220P-15402
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
Packing

Carrying

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.

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