Protection of Lithium Ion Batteries (one cell)

Monolithic IC MM1301

Outline

This IC provides protection for the MM1291 series of compact, high-precision type lithium ion batteries which

have been in use for some time. Precision of ±30mV is guaranteed between 0°C and +50°C, and this IC can

be used in applications where precision is crucial.
