MM3508A

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 MM3508A series are dual protection ICs designed for 2 to 4 cells lithium-ion or lithium-polymer battery packs, providing secondary protection. Equipped with a built-in timer circuit, they allow configurable detection delay times. A latch function enables the detection output to be held for a defined period, ensuring stable fuse blow timing. Additionally, after fuse disconnection, the IC can reduce high cell voltages to safe levels to help prevent battery degradation.

MM3508A features :

• Range and accuracy of detection/release voltage
• Range of detection delay time
• Low current consumption
• The fuse-cutting signal is output for a specified period of time. After the fuse is blown, the cell voltage is gradually discharged through an internal discharge resistor of approximately 60 kΩ (typical). The cell stops discharging when the cell voltage drops below the discharge stop (release) voltage.

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