Besides, put out an error signal (”L”) which inform that 8 D1 protection circuit is operating at the same time from pin8. (2) 1 The protection circuit reset and resort to ordinary condition 30v Ctrip ( “OFF” period needs 10us or more ) (3) DZ1 2 VIN (5V) if input signal is “OFF” when the premised 1~2msec passed. Rg When the output rises, the controlled time detect short 5 14 VLA541 circuit (Typ 2.6us) is set up so that on-time of IGBT can be secured properly. 4 VCC 47uF 13 It is possible to adjust that time by connecting the capacitor HC04 etc. (Ctrip) between pin2 and 4. 47uF VEE 6 VCC = 15V VEE = 10V Ctrip = 0 ~ 39pF (Rough guide , OPERATION FLOW ON DETECTING SHORTCIRCUIT 50V,ceramic) D1: Fast recovery diode (trr ≤ 0.2us) RP1H (SanKen) etc. PRECAUTION START (1) Voltage compensate capacitors are expected to be located (1) D1 requires approximately the same voltage of power modules. (2) If reverse recovery time of D1 is long, pin1 is applied high voltage. as close as possible from the hybrid IC. DETECTION OF SHORT CIRCUIT In that case, counterplan for protection which insert a zener diode between pin 1 and 6 is necessary like above diagram. (3) In case pin 2 is operating, the Ctrip is expected to be wired as close as possible from pin 2 and pin 4.

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 Storage 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. 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) Extended storage 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. 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 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. 4 HYBRID IC VLA541-01R TENTATIVE Hybrid IC for driving IGBT modules Marketing division, Marketing planning department 6-41 Tsukuba, Isahaya, Nagasaki, 854-0065 Japan Keep safety first in your circuit designs! ·ISAHAYA Electronics Corporation puts the maximum effort into making semiconductor products better and more reliable, but there is always the possibility that trouble may occur with them.
