bq29330 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-patible interface to extract battery parameters such as battery voltage, individual cell voltages, and control output status. Other parameters such as current protection thresholds...
