Protection IC for 3-5 Cell Batteries with Secondary Protection Function Protection IC for Lithium Ion/Lithium Polymer 3-5 Cell Secondary Battery
The <MM3684 series> features built-in secondary protection function compliant with international standards for electronic tools, which contributes to improved safety during use.
The <MM3684 series> features the additional functions of temperature protection and multi-stage overcurrent protection. These help to achieve a low consumption current and better space efficiency that could not be achieved with existing circuit layouts, and also helps to improve safety of lithium ion batteries.
Built-in overcharge, over-discharge and overcurrent protection functions.
3-stage discharge overcurrent protection
Detection of 2 values of high and low temperatures with an external NTC to protect battery packs
Built-in secondary protection function to drive external FET for FUSE
Intermittent operation with temperature protection for a low consumption current
Over-discharge detection voltage switch function (2 values can be set)
