Dear everyone,
Thank you very much for reading my Max712/713 problem.
I've wired a max712/713 to charge a 2cells NiMh battery pack, please find the design attached.
However, when I start charging, DRV pin voltage is "switching" and regulation isn't done properly, it's like the charge is switching between on and off.
Please find attached several graphs about the voltages I monitored with this problem.
I hope you'll be able to help me, I'm on it since two weeks now and I'm not able to figure out why is this happening...
Please feel free to ask any questions, I can do any measurements that can help you to understand my problem.
Thank you very much.
BR.
