The SC8931 is a highly integrated switch-mode buck charger for 1-2 cell Li-ion battery applications. It supports 4-13.5V input, up to 3A charging current and provides battery charge management functions including trickle charge, constant current charge, constant voltage charge, charge termination and charging status indication. The SC8931 supports flexible charge current option, and the user can program the current freely through external resistor for different applications. With the charger management function, the IC can be used to charge 1-2 cell Li-ion battery. The SC8931 supports input current limit, input under voltage and over voltage protections, internal cycle by cycle current limit, battery short circuit protection, and output over voltage protection. It also offers over temperature protection to ensure safety under different abnormal conditions. The SC8931 is available in QFN-3*3(FC) package.
