NCP802
NCP802 is Highly Integrated Lithium Battery Protection manufactured by onsemi.
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 circuits the pack by turning off one of these MOSFET switches, which disconnects the current path. Internal delay circuitry minimizes external ponent count.
