Hey, I hope I can once again save time by asking a question which has probably been answered a million times before (I can't find info when I search what I think are key terms).
Here's the problem. I have a circuit powered off of one battery (3.6V lithium coin cell). How do I disconnect my circuit from the power when my coin cell battery goes below 2V so that a user doesn't leave a device turned on for too long in between recharges?
Currently if you leave this device on for a long time, it will draw most of the charge out of the battery leaving it at 1V or less which is very bad for lithium batteries.
Any easy fixes? Terms I should search for?
