        According to the distributors, there are two versions of the ADM691A. The ADM691A with a 35ms minimum reset timeout and the ADM691AA with a 140mS minimum reset timeout. I can't find any discussion in the data sheet that explains this. Can anyone point me in the right direction? Thanks …

        Hello ADM691A datasheet figure 21 says the rechargeble battery. The input power line is connected to battery line and Vout line in figure 21. Is this description typo ? I think that above connection is not needed because a recharge is done by (vout -vbatt/R) . And, in the case of …

        Hello Migs: OK, that explains what’s going on. Thanks for your help. It seems to me that the ADM691A really should have been called something else to avoid this confusion. ADM691B would have worked. Keith

        Hi Terumasa, You are absolutely correct. That seems to be a drawing error, the two lines should not be connected. i'll log this into the datasheet feedback so it will be corrected whenever the datasheet is being revised the next time. thanks for pointing this out. Ren
