2 bq3050 Device-Based Circuit Module

The bq3050/bq29440-based circuit module is a complete and compact example solution of a bq3050

circuit for battery management and protection of Li-Ion or Li-Polymer packs. The circuit module

incorporates a bq3050 battery monitor IC, bq29440 independent overvoltage protection IC, and all other

components necessary to accurately predict the capacity of 2-series, 3-series, or 4-series cells.

2.1 Circuit Module Connections

Contacts on the circuit module provide the following connections:

• Direct connection to the cells: 1N (BAT–), 1P, 2P, 3P, 4P (BAT+)

• To the serial communications port (SMBC, SMBD, VSS)

• The system load and charger connect across PACK+ and PACK–

• To the system present pin (SYS PRES)
