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 tim...
