DESCRIPTION  
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 compatible 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 of the battery  
management system.

The bq29312 provides safety protection for overcharge,  
overload, short-circuit, overvoltage, and undervoltage  
conditions in conjunction with the battery management  
host. In overload and short-circuit conditions, the bq29312  
turns the FET drive off autonomously dependant on the  
internal configuration setting.
