　　The CS213 is the 1-cell protection IC for

　　lithium-ion/lithium-polymer rechargeable battery pack.

　　This protection IC was developed for use with

　　lithium-ion/lithium polymer 1-cell serial batteries.

　　It detects over-charge, over-discharge, discharge

　　over-current and other abnormalities, and functions to

　　protect the battery by turning off the external FETs.

　　The IC also has a built-in timer circuit (for detection

　　delay times), so fewer external parts can be used in

　　protection circuit configuration.

　　The tiny package is especially suitable for compact

　　portable device, i.e. slim mobile phone and Bluetooth

　　earphone.

　　Application

　　
Mobile phone battery packs

　　
Digital camera battery packs

　　
Bluetooth earphone Li-ion battery module
