DESCRIPTION VLA500K is a hybrid integrated circuit designed for driving n-channel |GBT modules in any gate-armplifier application. Electrical isolation voltage between input and output is 4000Vrms (for 1minute).This device include the isolated type DC-DC converter for a Gate drive. Therefore design of the gate power supply is not required. The system of built-in short circuit protection provide a margin to time by function to maintain reverse bias for a predetermined time after the detection of short circuit.

In that case , counterplan for protection which insert a zener diode between pin21,22 and 30 are necessary like above diagram. {5) When you make late speed of reverse bias at the time of short circuit protection operation, please adjust and connect a capacitor between the 21,22 and 27. SUS ISAHAYA ELECTRONICS CORPORATIONOPERATION OF PROTECTION CIRCUIT (1) In case the gate voltage is H and the collector valtage is high, this Hybrid IC will recognize the circuit as short circuit and immediately reduce the gate voltage . Besides, put out a fault sign (L) which inform that protection circuit is operating at the same time from pin 28. (2) The protection circuit reset and resorted to ordinary condition if input sign is L when the predetermined time(1 ~ 2ms) passed. (L" period needs 15us or more } (3) When the output rises, the controlled time detect short circuit (Typ 2.8us) 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 pin 21,22 and 29.

HYBRID IC VLA500K-01R DRIVER FOR IGBT MODULES ADJUSTMENT OF OUTPUT FALL TIME (When the protection circuit is operating) In case you want to decrease the speed of reverse bias when the protection circuit is operating, you can adjust that speed by connecting the capacitor (Cs) between pin 21,22 and 27.

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 Packing The materials used in packing Hics can only withstand normal external conditions. When exposed to outside shocks, rain and certain environmental contaminators, the packing materials will deteriorates. Please take care in handling. Carrying 1) Don't stack boxes too high. Avoid placing heavy materials on boxes, 2) Boxes must be positioned correctly during transportation to avoid breakage. 3) Don't throw or drop boxes. 4) Keep boxes dry. Avoid rain or snow. 5} 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 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 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 fram 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.
