How to make a simple Li-Ion Battery Charger Circuit Using IC LP2951

By : Alok kumar

Today's post explains a very simple yet safe Li-Ion battery charger circuit using just a single IC LP2951. Unlike lead acid batteries the one good thing about the Li-Ion batteries is that they can be charged at 1C rate (simply fast charging) initially. It means the battery's charging current can be as high as the rated AH (Ampere*Hour) of the li-ion battery at the onset. The design presented in this post can be used for charging a single 3.7V Li-ion cell or a standard cell phone battery externally at a relatively slower rate.
