MM3645

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 MM3645 series are protection ICs for Lithium-ion or Lithium-polymer secondary battery, developped using a high voltage CMOS process. They protect the battery pack or system from overcharge, overdischarge, overcurrent and other fault conditions by controlling FET switches. Overcurrent detection is achieved with high accuracy and improved temperature dependence through the use of an external chip resistor. Additionally, the inclusion of a charge-off mode reduces system standby current and prevents Lithium-ion battery from discharging when the system is off.

MinebeaMitsumi Lithium-Ion battery management ICs are made in Japan. High quality products, they will match your application needs.
