MinebeaMitsumi offers a wide range of battery ICs, supporting configurations from single-cell to multi-cell battery packs. These ICs are suitable for a variety of applications, from mobile devices to electric bicycles. Designed with high detection accuracy and rich functionality, these battery ICs ensure safe charging and reliable protection of rechargeable batteries. 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. MinebeaMitsumiMM3835W is a linear charge control device for single-cell lithium-ion and lithium-polymer batteries, offering high-precision charge current control from 3mA to 1000mA. This makes it particularly suitable for mobile devices using low-capacity batteries. It is available with multiple charge voltage options (4.20V, 4.35V, 4.10V) to support a wide range of battery types. Safe charging is ensured through dynamic adjustment of charge voltage and current based on temperature, in compliance with the JEITA battery temperature profile.
