Selection of a fuel gauge is dependent on the key characteristics most important for your project:
ease of design, length of design-cycle, accuracy, load and temperature conditions, quiescent current requirements, any special features, size and cost targets.
Here are some guidelines:

Here are some guidelines:
•Choose ModelGauge m5 (MAX17055, MAX17201, MAX17205, MAX17211, MAX17215) for:
>Easiest design – No characterization required (EZ Config), simple software driver
>Highest accuracy – Error <3%
>Best performance at corner conditions
•High empty voltage (>3.3V)
•High loads ( >C/4)
•Low temperature < 10°C
•Choose MAX17048 or MAX17055 for lowest quiescent current
>MAX17048 has 3µA Iq
>MAX17055 has 7µA Iq
•Choose MAX17055 for special features:
>Time-to-empty (TTE) under constant power or load, time-to-full (TTF), dynamic power
•Choose MAX17201, MAX17205, MAX17211, MAX17215 for additional special features:
>MAX17055 features + non-volatile memory, pack-side, multi-cell, authentication, Cycle+ age forecast
•For lowest size & cost:
>MAX17048, MAX17049 / MAX17058, MAX17059 WLP is smallest / least expensive
>MAX17055 WLP
>MAX17201, MAX17205, MAX17211, MAX17215 WLP
