SLUSB20 – NOVEMBER 2012
STANDARD DATA COMMANDS
Thebq27520-G4 uses a series of 2-byte standard commands to enable system reading and writing of battery
information. Each standard command has an associated command-code pair, as indicated in Table 2. Because
each command consists of two bytes of data, two consecutive I²C transmissions must be executed both to
initiate the command function, and to read or write the corresponding two bytes of data. Additional details are
found in the bq27520-G4 Technical Reference Manual.
