8 Detailed Description
bq27531-G1
SLUSBE7C – MARCH 2013 – REVISED JANUARY 2016
8.1 Overview
The fuel gauge accurately predicts the battery capacity and other operational characteristics of a single, Li-
based, rechargeable cell. It can be interrogated by a system processor to provide cell information, such as
remaining capacity and state-of-charge (SOC) as well as SOC interrupt signal to the host.
The fuel gauge can control a bq2419x Charger IC without the intervention from an application system processor.
Using the bq27531-G1 and bq2419x chipset, batteries can be charged with the typical constant-current,
constant-voltage (CCCV) profile or charged using a Multi-Level Charging (MLC) algorithm.
