2 bq27410-Based Circuit Module
The bq27410-based circuit module is a complete and compact example solution of a bq27410 circuit for
battery management. The circuit module incorporates a bq27410 battery gas gauge integrated circuit (IC)
and all other components necessary to accurately predict the capacity of 1-series Li-ion cell.
2.1 Circuit Module Connections
Contacts on the circuit module provide the following connections:
• Direct connection to the battery pack (J1 or J6): PACK+, PACK–
• To the serial communications port (J3): SDA, SCL, and VSS
• The system load and charger connect across charger and load (J5 and J4): CHARGER–/LOAD– and
CHARGER+/LOAD+.
• Access to signal outputs (J2): BIN, and GPOUT
