Hello,
It's kinda the first time when using this kind of forums.
I'm a student at Electrical Engineering and Computer's Science.
I'm trying to build some kind of plasma speaker using SG3525 but i do have some questions regarding the pins of the SG3525AN IC.
First i'm trying to drive 2 mosfets for obtaining an electric arc (schematic depicted in page 6, fig. 11) but after connecting the 15-13 pins to Vcc source; the Rt, Ct and pin 7 (discharge) to the ground i have oscillation at pin 4 in some form of almost instantaneous impulses on the oscilloscope but the outputs A (11) and B(14) appear to have 0V between them and GND.
Can anyone answer me why is that happening?
Regards,
Bogdan
