APPLICATIONS

Protection IC for Two-Cell Lithium-Ion Battery

Pack.

DESCRIPTION

The SS6802 battery protection IC is designed

to protect lithium-ion batteries from damage due

to

overcharging,

overdischarging,

and

overcurrent for two series cells in portable

phones and laptop computers. It can be a part

of the low-cost charge control system within a

two-cell lithium-ion battery pack.

Safe and full utilization charging is ensured by

the accurate

±30mV overcharge detection.

Three

different

specification

values

for

overcharge protection voltage are provided for

various protection requirements. The very low

standby current drains little current from the

cells while in storage.
