About discharge resistor for soft shut down on activity of short circuit protection
When the short circuit protection works, the soft gate shut down circuit works to suppress collector surge voltage of IGBT.
When short circuit protection circuit operates, the gate voltage descends slowly by the discharge circuit in dotted lineof following figure.
In this figure, main discharge resistor is Rs1. But Rs1 is not installed in HIC at the initial state.
So please solder the chosen resistor(1W class) certainly.
And please set Rs1 by the following equation.

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 200mA.
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 200mA
Idrive : Gate average current

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 error signal (”L”) which inform that protection
circuit is operating at the same time from pin 7.
(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 besecured properly.
It is possible to adjust that time by connecting the capacitor (Ctrip) between pin28 and 27.

LATCH & TIMER RESET SYSTEM IN SHORTCIRCUIT PROTECTION CIRCUITOPERATION FLOW ON DETECTING SHORT CIRCUIT

Once 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.

PRELIMINARYVLB506-01R
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
PackingCarryingThe 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.
