MM3280

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. MM3280 series are protection ICs designed using a high voltage CMOS process, providing overcharge, overdischarge and overcurrent protection for rechargeable Lithium-ion or Lithium-polymer batteries. They can detect a variety of fault conditions in single-cell rechargeable lithium-ion or lithium-polymer batteries, including overcharge, overdischarge, discharge overcurrent, short-circuit, optional charge overcurrent, and optional overvoltage from the charger. Each IC integrates four voltage detectors, a short-circuit detection circuit, reference voltage sources, an oscillator, a counter circuit and logical circuits.

MM3280 features :

• Range and accuracy of detection/release voltage
• Range of detection delay time
• 0V battery charging function selectable : "Allow" or "Prohibit"
• Timer function for overload detection (function for pulse charging)
• Low current consumption

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