Description
The bq29312A 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 bq29312A also integrates an I2C compat- ible interface to extract battery parameters such as cell voltages and control output status. Other par- ameters such as current protection thresholds and delays can be programmed into the bq29312A to increase the flexibility of the battery management system. The bq29312A provides safety protection for over- charge, overload, short-circuit, overvoltage, and undervoltage conditions with the battery management host. In overload and short-circuit conditions, the bq29312A turns the FET drive off autonomously dependant on the internal configuration setting. View All Description in Datasheet |
