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.
These functions comprise a protection circuit, with few external parts, for lithium ion batteries.
