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. MinebeaMitsumiMM3358 is a linear charge control IC for 1-cell Lithium-Ion and Lithium-Polymer batteries. It integrates a power MOSFET and a reverse-current blocking circuit, enabling charge control without the need for an external sense resistor or reverse-blocking diode. The chip temperature detection function can limit the temperature rise during high power charging . It also enables temperature-based charge control. MM3358 uses a small PLP-10 pin package.
