MM3659

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. MinebeaMitsumiMM3659 is a 4.5A switch-mode charge controller with an integrated power path and USB OTG support. Its synchronous rectification and switching charge control enable low heat generation while delivering high-efficiency system power and battery charging. By integrating key peripheral  components, it eliminates the need for costly current-sense resistors, external power MOSFETs, and reverse-current protection diodes, significantly reducing component count. Furthermore, power management, system drive, and charge control are all consolidated into a single chip, helping to streamline the design process and reduce development time.
