DESCRIPTIONThe bq29330isa 2-series, 3-series, and 4-series cell lithium-ion battery pack full-protection analog front end
(AFE)IC that incorporatesa 2.5-V, 16-mA and 3.3-V, 25-mA low dropout regulator (LDO). The bq29330 also
integrates anI2 C-compatible interfaceto extract battery parameters such as battery voltage, individual cell
voltages, and control output status. Other parameters suchas current protection thresholds and delays can also programmed into the bq29330to increase the flexibilityof the battery management system.
