Control of Lithium Ion Battery Charging and Discharging MM1248  
MITSUMI  
Control of Lithium Ion Battery Charging and Discharging  
Monolithic IC MM1248  
Outline  
This IC was developed for use in controlling charging and discharging of lithium ion batteries (battery modules  
with three cells connected in series). In charging control, the voltage of the battery module as a whole is  
controlled in constant-voltage control. Discharge control and monitoring of overvoltage rely on monitoring of  
the voltages of individual cells.  
Features  
1. Charging control voltage  
VBATH=12.465V 1.5ꢀ (Ta=  
-20°C~70°C)  
2. Overcharge detection voltage  
VCELL=4.335V 1.5ꢀ (Ta=  
-20°C~70°C)  
3. Internal circuit for setting dead time (for overvoltage detection, discharge control)  
4. Low consumption current on overdischarge IBATH3=1µA typ.  
5. High-precision internal overvoltage detection startup circuit (cell voltage 4.2V or higher at end of charging)
