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, Nchannel 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 component count.
