Connecting the bq30z554/bq29412 Circuit Module to a Battery Pack
shows how to connect the bq30z554/bq29412 circuit module to the cells and system
load/charger.
The cells must be connected in the following order:
1. 4-Cell Pack: 1N (BAT–), 1P, 2P, 3P, then 4P (see
for definitions)
2. 3-Cell Pack: 1N (BAT–), 1P, 2P, and then connect 4P and 3P together
3. 2-Cell Pack: 1N (BAT–), 1P, and then connect 4P, 3P, and 2P together
To start charge or discharge test, connect the SYS PRES pin to the Pack– pin to set SYS PRES state. To
test sleep mode, disconnect the SYS PRES pin.
