SS6804

Three/Four-cell Lithium-Ion Battery Protection IC

FEATURES

DESCRIPTION

Ultra-low quiescent current, 17µA (4-cell, Vcell = 3.5V).

Ultra-low power-down current, 2.2µA (4-cell, Vcell = 2.3V).

Wide supply voltage range: 2V to 18V.

Precision over-charge protection voltage:

4.35V±30mV for the SS6804A

The SS6804 is designed to protect a lithium-ion

battery from damage or degraded lifetime due to

over-charging, over-discharging and over-current

for three- or four-cell lithium-ion battery powered

systems such as notebook PCs.

4.30V±30mV for the SS6804B

It provides the cell-balancing "bleeding" function

to automatically discharge the over-charged cell

until the over-charge condition is eliminated.

4.25V±30mV for the SS6804C

4.20V±30mV for the SS6804D

Externally set over-charge, over-discharge and

over-current delay time.

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.

Built-in cell-balancing bleeding network under

over-charge condition.

Three detection levels for over-current protection.

APPLICATIONS

Protection IC for three/four-cell lithium-ion battery packs.
