NCP800

Lithium Battery Protection

Circuit for One Cell

Battery Packs

continuously powers it. In order to maintain cell operation within

specified limits, this protection circuit senses cell voltage 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 NCP800 open circuits the

pack by turning off one of these MOSFET switches, which

disconnects the current path.
