High Efficiency, Synchronous Boost Charger for Two/Three cell Li ion Battery with Cell Balance Function
SC8922A
The SC8922A is a highly integrated switch-mode boost charger 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 SC8922A supports up to 3A charge current, and the user can program the current freely through external resistor for different applications. The SC8922A 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 SC8922A is available in 4x4 QFN-24 package.
