Two-Cell Lithium-Ion Battery Protection IC

FEATURES

DESCRIPTION

Ultra-low quiescent current at 10mA (V_CC=7V,

The SS6802 battery protection IC is designed to

protect lithium-ion batteries from damage due to

over-charging, over-discharging, and over-current

for two-series cells in portable phones and laptop

computers. It can be a part of a low-cost charge

control system within a two-cell lithium-ion battery

pack.

V_C=3.5V).

Ultra-low power-down current at 0.2mA (V_CC

=3.8V, V_C=1.9V).

Wide supply range: 2V to 18V.

Precision over-charge protection voltage

4.35V ± 30mV for the SS6802A

4.30V ± 30mV for the SS6802B

Safe charging with full utilization 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.

4.25V ± 30mV for the SS6802C

Built-in delay circuits for over-charge, over-discharge

and over-current protection.

Over-charge and over-discharge delay time can be

extended by external capacitors.

Built-in cell-balancing bleeding network under

over-charge condition.
