BQ25155: fuel gauge solution

Hello，

We intend to use BQ25155 in our system to provide battery management, and the qusetion is:

witch fuel gauge IC is recommended to use with BQ25155? The main function we want is SOC.

or any feature of this chip can provide this function? like ADC VBAT Measurement, canvert voltage into SOC, is it reliable?

by the way: our system has to work on a ring-sized device, so the chip size is an important consideration.

thanks for answering!
