MC33351A Advanced Information Lithium Battery Protection Circuit for Three Battery Packs The MC33351A is a monolithic lithium battery protection circuit that is designed to enhance the useful operating life of three cell rechargeable battery packs. The MC33351A is specifically designed to be placed in a lithium battery pack where the battery cells continuously power it. In order to maintain cell operation within specified limits, the protection circuit senses cell voltages, and discharge current, and correspondingly controls the state of two P–channel MOSFET switches. These switches are connected in series with the positive terminal of the third cell and the positive terminal of the battery pack.
