PRECAUTION

(1) Voltage compensate capacitors are expected to be located as close as
possible from the hybrid IC.
VD=15V +/-5%
VIN= 5V +/-5%
(2) D1 requires approximately the same voltage of power modules.
C1 ~ 4=100μF 50V(Low impedance)
(3) If reverse recovery time of D1 (D2) is long, pin23 (pin22) is applied high voltage.
In that case, counterplan for protection which insert zener diode between
pin 18 and 22 (pin 27 and 23) is necessary like above diagram.
(4) In case pin 21 or 24 are operating, the Ctrip is expected to be wired as close as
possible from pin. (Less than 5cm coming and going)
※In case of not operating, please pin 21 or 24 are open.
(5) Minimize the area of closed circuit of gate circuit and input gate signal circuit
so as not to be affected by induction noise.
(6) When the built in short-circuit protection circuit need not be used,
Ctrip1,2 : Depended on RG1,2
(Please refer to the
“ ttrip-Ctrip CHARACTERISTICS “ in page3)
Cs1,2 : Please refer to the
“ ts-Cs CHARACTERISTICS “ in page6)
Z1,4 : 30V
DZ2,3,5,6 : 18V
D1,2 : First recovery diode( trr : 0.2μs max )
RP1H(Sanken) etc.
PC1,2:TLP785(TOSHIBA) etc.
please connect resistance of 4.7k ohm between pin 17 and 22 (pin 23 and 28).
At that time, D1 (D2) and Dz1 (DZ4) are not require, and pin 16 and 29 are not
necessary to be connected.
(7) Pin 1 and 42 are for test pin, so pin 1 and 42 are not to be connected electrically to other line.
