Block Diagram
Protection of Lithium Ion Batteries (two cells in series) MM1292
Note 1. 45µA max. (current consumption during operation of overcharge detection section) flows to input
protection resistor R1.
Note 2. 0.3µA max. (when cells are balanced) flows to input protection resistor R2. When the cells are not
balanced, the current increases to wards correction.
