DESCRIPTION  
The bq29330 is a 2-, 3-, or 4-cell lithium-ion battery pack full-protection analog front end (AFE) IC that  
incorporates a 2.5-V, 16-mA and 3.3-V, 25-mA low dropout regulator (LDO). The bq29330 also integrates an  
I2C-compatible interface to extract battery parameters such as battery voltage, individual cell voltages, and  
control output status. Other parameters such as current protection thresholds and delays can also be  
programmed into the bq29330 to increase the flexibility of the battery management system.
