Stacking multiple bq2941x Li-ion secondary voltage protectors

Posted: 15 Sep 2008 ?? ?Print Version ?Bookmark and Share

Keywords:TI application note? Li-ion? secondary voltage protectors?

Li-ion battery applications, requiring five or more series cells, can make use of standard 4-series-cell secondary voltage protectors, such as the bq2941x series. The devices can be stacked as necessary and outputs of individual devices can be combined with optocouplers to produce a single alarm signal if any cell exceeds the threshold. In addition, for undervoltage protection, TLV3011 nanopower comparators may be easily stacked to provide a single alarm signal.
