General Description

FS325 is a series of lithium-ion and

lithium-polymer rechargeable battery protection

ICs with high accurate voltage detection and

delay circuits.

These ICs are suitable for protection of single

cell lithium-ion or lithium polymer battery packs

from over charge, over discharge and over

current.
