I'm looking to design a battery charger with built in data-logging. The requirements were I2C, capable of charging to 4.35V, 1 cell, and being able to read the charge current and voltage via I2C for the data logging.
I've spent a few hours looking at TI's offerings, and found the following
BQ25871 - 42DSBGA
BQ25892 - 24WQFN
The second would work, but has only a 7-bit ADC. The first is my preference - it's very simple and meets my needs, and even better, has a 10-bit ADC built in for measuring charge current/voltage. However, it's in BGA form, and 0.4mm pitch at that. Even just a breakout board to do prototyping looks pricey.
Took a few hours to find these 2, filtering out other TI options. I shudder to try and go through a handful of other manufacturers and do the same exercise.
Is working with this package size feasible and/or worth it?
