General 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.
