BQ24715: Gas gauge for Bq24715

Hello, 

I am looking for charger with below specifications .

System loads - 12V@360mA, 5V@6A and 3.3@2A (Not continuous) when required it can take current from battery also. 

Input -AC  Adaptor or USB Type C power adaptor 

Input voltage - 12V@3A or 15V @3A or 20V@3A

For above specification I am planning to use "Bq24715 ?(NMDC charger) . I am looking for suitable Gas gauge for the same. 

I dont require Cell balancing , so you can suggest Single cell li ion gas gauge. BQ24715 is SMbus based , So I reuiqre gas gauge with SMbus based.
