Overview
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 circuits the pack by turning off one of these MOSFET switches, which disconnects the current path.
Internal delay circuitry minimizes external component count.
