NCP802 Highly Integrated Lithium Battery Protection Circuit for One Cell Battery Packs The NCP802 resides in a lithium battery pack where the battery cell continuously powers it.

This circuit senses cell voltage, charge current, and discharge current, and correspondingly controls the state of two, N channel MOSFET switches.

These switches reside in series with the negative terminal of the cell and the negative terminal of the battery pack.

During a fault condition, the NCP802 open circu
