MITSUMI Protection of Lithium Ion Battery (three cells in series) MM1309 Protection of Lithium Ion Batteries (three cells in series) Monolithic IC MM1309 Outline This is a 3-cell series protection IC is for protecting a lithium ion battery from overcharging and excess discharging. If abnormalities occur during charging and excess voltage is applied, it has a function that turns off the external FET switch (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.
