VLA586-01R
GATE DRIVER FOR Full-SiC MODULEOPERATION OF PROTECTION CIRCUIT(1)FMF800DX-24A shunts the current fixed ratio of drain current to terminal of R1a(R2a).
This shunted current flows to detecting resistor(16Ω). This unit detects the short circuit condition by monitoring
voltage drop of detecting resistor.
(2) In case the input signal is “ON” and the terminal voltage of R1a(R2a) is high, this unit will recognize the circuit
as short circuit and immediately reduce the gate voltage. Besides, put out Fo signal (”L”) which inform that protectioncircuit is operating at the same time from CN1-4(CN1-5).
(3) The protection circuit resets and resorts to ordinary condition if input signal is “OFF” when the premised 1~2msec
passed. ( “OFF” period needs 10us or more )LATCH & TIMER RESET SYSTEM IN SHORTCIRCUIT PROTECTION CIRCUIT

Once the short-circuit protection circuit starts, it shuts down
the gate output and keeps Fo output, causing the latch status.
This status is canceled if the input signal is OFF when specifictime passed after the activation of the short-circuit protectioncircuit. Then, gate output depending on input signals becomespossible. If the input signal is ON when specific time elapses,
the latch status is not canceled: it is canceled 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.

GATE DRIVER FOR Full-SiC MODULEFOR SAFETY USINGGreat detail and careful attention are given to the production activity of Devices, such as the development, thequality of production, and in itʼs reliability. However the reliability of Devices depends not only on their own factors
but also in their condition of usage. When handling Devices, please note the following cautions.

CAUTIONS
Packing

Carrying

The materials used in packing Devices 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 Devices, please observe the following notices or possible deteriorationof their electrical characteristics, 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.

Extendedstorage

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

Maximum
ratings

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

Polarity

To protect Devices from destruction and deterioration due to wrong insertion, makesure of polarity in inserting leads into the board holes, conforming to the external viewfor the terminal arrangement.
