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.
Application

Mobile phone battery packs

Digital camera battery packs

Bluetooth earphone Li-ion battery module
