3 to 5cells lithium-ion/lithium-polymer battery protection IC
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.
