Other Parts Discussed in Thread: BQ25703A, , BQ25723, BQ25730
Tool/software:
I'm designing a battery controller for a client and I'm struggling to understand the differences between some of these charge controllers. The system uses a 4-series LiPo battery, charges from a 15V or 18V AC-DC converter, and requires I2C control of the charger, so I was looking at the sub-$2.00 buck-boost controllers, which look to be the BQ25713, BQ25713B, BQ25703A, BQ25723, and BQ25730. Other than that last one supporting up to 5 cells in series, I cannot figure out what the meaningful differences between any of those products are. Can someone help me understand what I should be looking at to compare them? Thanks!
