Description

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.
