The MM3280EA7YRE from MinebeaMitsumi is a high-voltage CMOS protection IC specifically designed for rechargeable Lithium-ion and Lithium-polymer batteries. This IC provides essential protection functions for single-cell battery applications, including detection and prevention of overcharge, overdischarge, discharging overcurrent, and short circuits. Optional detection for charging overcurrent and overvoltage charger conditions are also available.
Key electrical specifications include a wide range of detection and release voltages for overcharge (3.6V to 5.0V) and overdischarge (2.0V to 3.0V), with high accuracy. It also features detection for discharging overcurrent (+50mV to +300mV) and charging overcurrent (-300mV to -50mV). The IC offers selectable detection delay times for various fault conditions, ranging from microseconds for short detection to seconds for overcharge detection.
With low current consumption in normal mode (typically 3.0µA) and standby mode (max 0.1µA), the MM3280EA7YRE is suitable for power-sensitive applications. It is available in SSON-6J and SOT-26A/B packages, facilitating integration into compact electronic designs.
The overcharge detection voltage can be set from 3.6V to 5.0V in 5mV steps, with an accuracy of ±20mV.
The short detection voltage is selectable from 0.7V, 0.8V, or 0.9V, with an accuracy of ±100mV.
Standby current is maximum 0.1µA under charger connection release condition, and maximum 0.5µA under voltage release condition.
The device is offered in SSON-6J and SOT-26A or B packages.
Normal mode current consumption is typical 3.0µA and maximum 6.0µA.
Yes, the overdischarge detection delay time can be selected from 20ms, 24ms, 96ms, 125ms, 128ms, or 144ms.
Yes, charging overcurrent detection voltage is from -300mV to -50mV in 5mV steps, with an accuracy of ±20mV. The detection delay time is selectable from 4ms to 96ms.
