Protection of Lithium Ion Batteries (four cells in series)

Outline\nThis IC provides protection for lithium ion batteries in the event of overcharging, overdischarging and overcurrents. When anomalies occur during charging or at other times and excessive voltages are applied, after a certain time has elapsed for each cell an external FET switch is turned of 1.
