Looking for TCA785 datasheet

[Sadegh.j]

Hi

I need to trigger the gate of the tyristors of a fully controlled 3-phase 6-pulse recitifier using a TCA 785. Could some one please give me the circuit. I believe that this is not difficult.

Thanks a lot

TCA785 is an very old ic , I think more than 20 years old, manufactured by Infineon (Siemens). You can find the data sheet of component in the Infineon web site.
