MM3635

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. MinebeaMitsumiMM3635 is a linear charge control device designed for single-cell Li-ion and Li-polymer batteries. It supports charging from 0V battery voltage, making it suitable for low-capacity batteries such as coin cells. The BAT regulation voltage can be configured to accommodate different battery types. It eliminates the need for an external sensing resistor and reverse-current protection diode, reducing both component count and heat generation. Additionally, it includes a safety feature that disables charging at high or low battery temperatures to protect the battery.
