DESCRIPTION
The AIC1804 is designed to protect the lithium-
ion battery from damage or degrading the lifetime
due to overcharging, overdischarging and
overcurrent for three-cell or four-cell lithium-ion
battery powered systems such as notebook PCs.
It can also provide the cell-balancing “bleeding”
function
to
automatically
discharge
the
overcharged cell until the overcharge condition is
released.
Safe and full utilization charging is ensured by
the accurate
±30mV
overcharge detection. Four
different specification values for overcharge
protection voltage are provided for various
protection requirements. The very low standby
current drains little current from the cell while in
storage.
APPLICATIONS
Protection IC for Three- or Four-Cell Lithium-Ion
Battery Packs.
