Monolithic IC MM3474 Series
Outline
MM3474 series is an overcharge, overdischarge and overcurrent protection IC for a lithium-ion / lithiumpolymer rechargeable secondary battery. Lithium-ion / lithium-polymer rechargeable secondary battery overcharge each cell, over discharge, and discharge overcurrent, short circuits can be detected. This supports 3 to 5 serial cells connected in series, and switches over to the desired no. of cells by sending High / Low signal to SEL terminal. This also provides the control terminals of output over discharge detection (SDC) and output over charge detection (SOC), which allows configuring an application with fewer external parts for 6 or more cells connected in series.
