For the BQ27531 fuel gauge, what the benefits are to having it directly linking to the BQ2419x family of chargers without the need to connect the 2419 IC to the host. How and what does the BQ27531 control the 2419x, what level of automation? Are there any issues with 4.1v charging with this part? Also, are there any known app notes to help with implementing/integrating this part in a system?
The customer is trying to decide between the 27531 or the use of a non-direct link charger-gas gauge circuit
