SS6821
Single-Cell Lithium-Ion Battery Protection IC
FEATURES
Reduction in board size with miniature SOT-23-5
package and few external components.
Ultra-low quiescent current of 7
μ
A (V
CC
=3.5V).
Ultra-low power-down current of 0.6
μ
A (V
CC
=2.2V).
Precision over-charge protection voltage
4.35V
±
50mV for the SS6821A
4.30V
±
50mV for the SS6821B
4.25V
±

Built-in delay-time circuits for over-charge, over-
discharge, and over-current protection.
Load detection function during overcharge mode.
Two detection levels for over-current protection.
APPLICATIONS
Protection IC for single-cell Lithium-Ion battery
packs.
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 in single-cell
lithium-ion battery powered systems, such as
cellular phones. The ultra-small package and
few external components make the SS6821
ideal for integration into the limited space of
of a battery pack.
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.
