SS6803
Three-cell Lithium-Ion Battery Protection IC
FEATURES
DESCRIPTION
Ultra-low quiescent current of 13µA (Vcell = 3.5V).
The SS6803 is designed to protect a lithium-ion
battery from damage or degraded lifetime due to
over-charging, over-discharging and over-current
for three-cell lithium-ion battery powered systems
such as notebook PCs.
It provides the cell-balancing "bleeding" function
to automatically discharge the over-charged cell
until the over-charge condition is eliminated.
Ultra-low power-down current of 1.3µA (Vcell = 2.3V).
Wide supply voltage range: 2V to 18V.
Precision over-charge protection voltage:
4.35V±30mV for the SS6803A
4.30V±30mV for the SS6803B
4.25V±30mV for the SS6803C
4.20V±30mV for the SS6803D
Externally set over-charge, over-discharge and
over-current delay time.
Built-in cell-balancing bleeding network under
over-charge condition.
Three detection levels for over-current protection.
Safe charging with full utilization is ensured by
the accurate ±30mV over-charge detection. Four
different specification values for over-charge
protection voltage are provided for various
protection requirements. The very low standby
current represents little drain from the cell while in
storage.
APPLICATIONS
Protection IC for three-cell lithium-ion battery pack.
