bq29312 Overview
The bq29312 is a 2-, 3-, or 4-cell lithium-ion battery pack protection analog front end (AFE) IC that incorporates a 3.3-V, 25-mA low-dropout regulator (LDO). The bq29312 also integrates an I2C patible interface to extract battery parameters such as cell voltages and control output status. Other parameters such as current protection thresholds and delays can be programmed into the bq29312 to increase the flexibility...
