Protection of Lithium Ion Batteries (two cells in series) MM1292  
MITSUMI  
Protection of Lithium Ion Batteries (two cells in series)  
Monolithic IC MM1292  
Outline  
This IC is for protecting a lithium ion battery from overcharging, excess discharging, and overcurrent. If  
abnormalities occur during charging and excess voltage is applied, it has a function that turns off the external  
FET switch when voltage is applied to each battery beyond a specified time (overcharging detection). It also  
has a function that turns off the external FET switch when the voltage for each battery falls below a set  
voltage, to prevent excess discharge when discharging the battery (discharging detection). At that time, the IC  
is switched to low current consumption mode. Also, when there is a large current flow due to shorting or other  
reasons, there is a function for turning off the external FET switch (overcurrent detection).  
These functions comprise a protection circuit, with few external parts, for lithium ion batteries.
