Hi All,
I'm would like to monitor a 12V battery from a microcontroller or x86 controller. I want to be able to make machine decisions based on the expected battery lifetime, similar to how laptops can monitor their batteries.
The range of voltages I would like to monitor would be 11V-13V and I have been having trouble finding A/Ds that handle that kind of voltage. I'm guessing that I need to use a voltage divider to get the voltage into the range that the A/D can handle. Would this be the right way to do this?
Thanks, Brian
