DESCRIPTION  
The bq24314A is a highly integrated circuit designed to provide protection to Li-ion batteries from failures of the  
charging circuit. The IC continuously monitors the input voltage, the input current, and the battery voltage. In  
case of an input overvoltage condition, the IC immediately removes power from the charging circuit by turning off  
an internal switch. In the case of an overcurrent condition, it limits the system current at the threshold value, and  
if the overcurrent persists, switches the pass element OFF after a blanking period. Additionally, the IC also  
monitors its own die temperature and switches off if it exceeds 140°C. The input overcurrent threshold is  
user-programmable.  
The IC can be controlled by a processor and also provides status information about fault conditions to the host.
