Single Cell Battery Power Solution Reference Design


Design files


This reference design shows the functionality and performance of a complete single-cell battery power solution using a coin-cell Li-Ion battery. It can be powered either by an external adapter or by an USB port. When the board is connected to a computer, the load current, state-of-charge, and much more information about the battery can be monitored on a GUI.
