Hi, I found one problem. The nand oscillator is only putting out a 5 volt timing signal. The IR2117 has a input low voltage lockout. I have to increase the voltage of the timing signal.
I guess not all 4000 series are the same, thing do change. The new used scope works well, it is fast, gives to much information and has to many buttons but I am happy to have it.
From the application notes it looks like the IR2125 is designed for a 12 volt battery charging circuit. The IR2117 is designed for resistive loads. I am proceeding with what I have. I will be happy if I can just get a MOSFET to trigger at this time and I will post results when available.
