If you're thinking of making a lithium end of charge indicator - don't do it!!!Hello;
Can any body tell is it possible with a opamp to get a LED flash after 2 sec and gets solid when LI ion battery gets fully charged.
Is their any option to achieve this by sensing battery voltage or current?
Battery cutoff at 4.1v
Just select a charge control chip that has a full charge indicator pin - I though most of them did.I am using a charge controller IC so its not a issue for me to cutoff battery when fully charge only issue is the indication scenario i needed.
It would have saved a lot of guessing if you'd put that in your first post.I am attaching circuit diagram please refer to it and provide a circuit diagram in here.
I already answered that question - flash the LED with an astable, and use the battery full pin to jam it so the LED stays on.It would have saved a lot of guessing if you'd put that in your first post.
If you can clarify what "LED flash after 2 sec and gets solid when LI ion battery gets fully charged" means I'm sure a solution is not far away? It appears that it already provides a solid LED indication when the battery is charged.
