DESCRIPTION

D
Requires No Offset Calibration  
Programmable Input/Output Port  
The bqJUNIOR series are highly accurate  
standalone single-cell Li-Ion and Li-Pol battery  
capacity monitoring and reporting devices  
targeted at space limited portable applications.  
The device monitors a voltage drop across a small  
current sense resistor connected in series with the  
battery to determine charge and discharge activity  
of the battery. Compensations for battery  
temperature, self–discharge, and rate of  
discharge are applied to the charge counter to  
provide available time-to-empty and time-to-full  
information across a wide range of operating  
conditions. Battery capacity is automatically  
recalibrated, or learned, in the course of a  
discharge cycle from full to empty. Internal  
registers include available time-to-empty, cell  
temperature and voltage, average current, and  
other status and control registers.  
Internal Time-Base Eliminates External
