MM3474

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 MM3474 series is an overcharge, overdischarge, and overcurrent protection IC designed for lithium-ion / lithium-polymer secondary battery packs. It supports battery configurations from 3 to 5 cells connected in series, with the number of cells selectable via a high/low signal input on the SEL terminal. The MM3474 series can also be cascaded to protect lithium-ion battery packs with 6 or more cells in series. Additionally, it features control terminals for output overdischarge detection (SDC) and output overcharge detection (SOC), enabling system configurations with fewer external components for applications using 6 or more series-connected cells.

MM3474 features :

• Range and accuracy of detection/release voltage
• Range of detection delay time
• 0V battery charging function selectable "Allow" or "Prohibit"
• The protection setting for 3-cells, 4-cells, or 5-cells can be configured using the SEL1 and SEL2 pins
• Battery charging and discharging can be controlled via the SDC and SOC pins.
• Low current consumption
