MM3474 series is an overcharge, overdischarge and overcurrent protection IC for lithium-ion/lithiumpolymer rechargeable batteries.
This supports 3 to 5 serials cells, and the number of cells can be switched over by inputting high/ low signal to SEL terminal.
The MM3474 series can protect a lithium-ion battery pack with more than 6 cells in series by connecting them in cascade.
It 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.
