MM3758

MinebeaMitsumi's charge control ICs are suitable for charging single-cell Li-ion and Li-polymer batteries and ensure stable charging through highly accurate voltage and current regulation. High safety is achieved through multiple protection features, including battery temperature monitoring via an external thermistor and a built-in charging timer. Additionally, the wide range of supported charging voltages and currents enables flexible system design, allowing compatibility with various battery types. MinebeaMitsumi MM3758 is a linear charge control solution for single-cell Li-ion and Li-polymer batteries. It eliminates the need for an external sensing resistor and reverse-current protection diode, allowing for a reduced component count and lower heat generation. The IC complies with standard battery temperature profiles and includes functions to limit charging current and voltage at both low and high battery temperatures, ensuring safe operation. A built-in dual-channel charge status flag provides detailed information on the charging state.
