In table 1, page 16, the VFloat and VRecharge voltages for Li-Ion batteries are way too low for that type of cell. I think that the designers mistakenly divided the voltage of a 12V battery by 6 (as for lead-acid batteries), instead of by 4, to represent the single cell Li-Ion voltage.
In the flow-chart diagram of page 20, the decision lozenge for IBAT> C/5 (C/10) has the wrong polarity, the sign should be < . Additionnally, I don't think that C/5 should be mentionned here; the correct wording should be IBAT< C/10.
It is not clear how we must program the FB pin voltage. This pin sets the constant-voltage that the battery will be charged at, during the absorbtion phase, if I understand correctly. Shouldn't the resistors feeding this pin be connected to a stable voltage source and not the battery itself ?
Where do we send ideas for new products, here at Analog Devices? Or is there a forum devoted to this?
Here I go answering my own post...
I just figured out how the FB pin works, so my (dumb) question above will not need to be replied to. Hopefully, this will be posted before Zack looses some time answering it.
But maybe a clearer mention in the datasheet that the voltage on the FB pin should be reduced to the equivalent of a Single Cell voltage!
No time lost here. He is currently out of the office and will relay your suggestions to him
Haha, no worries, and some good thoughts here. We are in the midst of a datasheet update so I can suggest some changes.
