1.2 Ordering Information
(1)
Using the FW_VERSION (0x0002) Control() subcommand returns 0x0109. See SLUSBN7 , bq27411-G1x System-Side
Impedance Track™ Fuel Gauge , data sheet for information on Control() subcommands.
(2)
Using the CHEM_ID (0x0008) Control() subcommand helps to differentiate between the bq27411-G1A (returns 0x0128), the
bq27411-G1B (returns 0x0312), and the bq27411-G1C (returns 0x0354). See SLUSBN7 , bq27411-G1x System-Side Impedance
Track™ Fuel Gauge , data sheet for information on Control() subcommands.
