SS6821

Single-Cell Lithium-Ion Battery Protection IC

n FEATURES

n DESCRIPTION

The SS6821 battery protection IC is

designed to protect a lithium-ion battery from

damage or reduced lifetime due to over-charge,

over-discharge, and/or over-current for single-cell

lithium-ion battery powered systems, such as

cellular phones. The ultra-small package and

fewer external components make the

SS6821 ideal for integration into the limited

space of a battery pack.

l Reduction in board size with miniature SOT-23-5

package and fewer external components.

l Ultra-low quiescent current at 7mA (V_CC=3.5V).

l Ultra-low power-down current at 0.6 m A (V

_CC=2.2V).

l Precision over-charge protection voltage

4.35V ± 50mV for the SS6821A

4.30V ± 50mV for the SS6821B

4.25V ± 50mV for the SS6821C

4.20V ± 50mV for the SS6821D

The accurate ±50mV over-charging detection

voltage ensures safe and full utilization

charging. Four different specification values for

over-charge protection voltage are provided for

various protection requirements. The very low

standby current drains little current from the cell

while in storage.

l Built-in delay time circuits for over-charge, over-

discharge, and over-current protection.

l Load detection function during overcharge mode.

l Two detection levels for over-current protection.

n APPLICATIONS

l Protection IC for single-cell Lithium-Ion battery

packs.
