DESCRIPTION  
The bq29330 is a 2-series, 3-series, and 4-series 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.
