Other Parts Discussed in Thread: BQ24765, BQ24610, BQ24747

Colleagues, one of my customers asked for a LiIon charger with Vin=12-16V, Ichrg=6A max, 2 cells LiIon. The automatic search gave up to 10 solutions: cf. http://focus.ti.com/en/download/aap/selectiontools/battery-chargers/charts-htmls/bq24xxx-2cell.html

Which is the most popular? From which to start?

Because Ichrg=6A, so, bq241xx is not git for this application. bq241xx only supports up to 2A. If the ambient temperature is high, the bq24765 is also not good for this application.

All other parts are good. Customer can choose the part according to their setup.

1. Do they need control ACFET and BATFET? bq2475x and bq24610 have ACDRV and BATDRV pin.

2. Do they support SMBus? bq24747 and bq24765 can support SMbus.

3. Do they need stand alone? bq24610 is stand alone IC (battery detection, TS..).
