SC8922

High Efficiency, Synchronous Boost Charger for Two/Three cell Li ion Battery with Cell Balance and Power Path Management Function

SC8922SC8922

SC8922

The SC8922 is a highly integrated switch-mode boost charger and system power path management device for 2/3 cells Li-ion battery applications. It is able to step up 4.5V~5.5V input voltage to up to 16V, and provide battery charge management functions including trickle charge, constant current charge, constant voltage charge, charge termination and charging status indication. Besides that, the IC can also provide cell balance function, so to reduce the cell voltage mismatch and increase the battery lifetime. The SC8922 supports up to 3A charge current, and the user can program the current freely through external resistor for different applications. With the power path management function and supplement mode, the IC can be used to charge 2/3 cells Li-ion battery and meantime provide power for system operation. The SC8922 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 charging safety timer, battery cell temperature monitor and over temperature protection to ensure safety under different abnormal conditions. The SC8922 is available in 4x4 QFN-24 package.
