SC8932A
SC8932A
High Efficiency, Synchronous Buck Charger for 1 2 cell Li ion Battery with MOSFET Integrated and I2C Interface
The SC8932A 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 provide battery charge management functions including trickle charge, constant current charge, constant voltage charge, charge termination and charging status indication. The SC8932A 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.SC8932A charges batteries with high efficiency, 5V to 3.5V@2A 95.5%, 9V to 7V@2A 97.1%. The SC8932A 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 and over temperature protection to ensure safety under different abnormal conditions. The SC8932A features I2C interface, so the user can easily set the input current limit, output current limit, switching frequency and output voltage through I2C.The SC8932A is available in QFN-3*3(FC) package.
