  • MinebeaMitsumi

One cell Li-ion/Li-polymer battery protection IC

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. Designed using a high-voltage CMOS process, MinebeaMitsumi ICs provide comprehensive protection for rechargeable Lithium-ion and Lithium-polymer batteries. They protect against overcharge, overdischarge, overcurrent during charging and discharging, as well as short circuits. They integrate four voltage detectors, a short-circuit detection circuit, reference voltage sources, an oscillator, a counter circuit, and logic circuits to ensure reliable and efficient battery protection. The MM3721 series are protection ICs for Li-ion rechargeable batteries, offering high-precision charge and discharge current detection through a current sensing resistor (Rsns). The MM3721 features two-step discharge overcurrent detection, enabling the system to respond appropriately in both normal discharge and high-current discharge mode.
