BQ29330,pdf(2, 3-, 4-Cell Lith
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.
The bq29330 provides safety protecTIon for overload, short circuit in charge, and short circuit in discharge conditions and can also provide cell overvoltage, battery overvoltage and battery undervoltage protection with the battery management host.
