The MM3280 series from MinebeaMitsumi are high-voltage CMOS protection ICs designed for rechargeable Lithium-ion and Lithium-polymer batteries. These ICs provide essential protection functions including overcharge, overdischarge, discharging overcurrent, and short circuit detection. Optional features include charging overcurrent and overvoltage charger protection.
Key electrical specifications include a wide range of detection and release voltages for overcharge and overdischarge, with accuracies typically within ±20mV to ±100mV. Overcurrent detection ranges from +50mV to +300mV for discharging and -300mV to -50mV for charging, with accuracies of ±10mV and ±20mV respectively. Short detection voltage is selectable from 0.7V, 0.8V, or 0.9V with ±100mV accuracy.
Detection delay times are also configurable, with options for overcharge, overdischarge, discharging overcurrent, charging overcurrent, and short detection. The ICs feature low current consumption, with typical normal mode consumption at 3.0µA and stand-by mode consumption as low as 0.1µA. The 0V battery charge function can be set to either prohibition or permission.
Available in SSON-6J and SOT-26A/B packages, these protection ICs are suitable for various battery management applications requiring reliable and precise protection.
