Any
The bq20z95/bq29412-based circuit module is a complete and compact example solution of a bq20z95
circuit for battery management and protection of Li-ion or Li-polymer packs. The circuit module
incorporates a bq20z95 battery monitor IC, bq29412 independent overvoltage protection IC, and all other
components necessary to accurately predict the capacity of 2-, 3-, or 4-series cells.
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)
•
The system load and charger connect across PACK+ and PACK-
•
To the system-present pin (SYS PRES)
