Overview

MITSUMI Protection for Lithium-Ion/Lithium Polymer Batteries (1 cell) MM3099/MM3199 Series Protection for Lithium-Ion/Lithium Polymer Batteries (1 cell) Monolithic IC MM3099/MM3199 Series April 26, 2004 Outline This is a protection IC developed for use with 1-serial cell lithium-ion/lithium polymer rechargeable batteries.

It provides a function to protect the batteries by detecting overcharge, overdischarge, discharge overcurrent, and other abnormalities and turning off the external Nch MOS FET.

The outputs of COUT pin (charge FET control pin) and DOUT pin (discharge FET control pin) are CMOS outputs, so that the external Nch MOS FET can be driven directly.

Key Features
