Hi,
I need some information on the battery that is used in the BQ4847.
From the data sheet it looks like that this is a lithium manganese dioxide coin cell, is that correct?
as this part is going to be obsolete, could you please provide shelf life information for this battery?
I know manufacturers usually say that it is 10years and it is also mentioned in the BQ4845 data sheet, I just wanted to be sure that this is the case in the TI part, meaning that the battery is "floating" and there is no current drawn from it till VCC is applied and therefore a 10years shelf life can be promised.
Thanks,
Ran
