Other Parts Discussed in Thread: BQ2014

anyone have any experience working with the bq2014 (not the H but with DQ comm)?  Packs are decrementing NAC at a fast rate.  Dropping down to zero in a matter of days. any suggestions?

    Yes I am using 2 banks of NI-MH cells and 2 bq2014 to indicate the state of charge. I am also facing similar problem as NAC decrements down to zero. Can it be a problem with PCB layout where Vsr < Vss ???

    I have tried shorting Sr Pin to Vss and then load NACH count through DQ line interface,the system works fine

    So it must be something to do with PCB layout/ tracks impedances???

    All suggestions are welcome!!!
