SC8802 is a synchronous 4-switch buck-boost charger controller. It is able to effectively manage charging no matter input/output voltage is higher, lower or equal to battery voltage. When system needs to discharge from battery, SC8802 will deliver desired output from the battery without extra efforts.SC8802 supports very wide input and output voltage range. It can support applications from 2.7V to 30V input range and 2V to 30V output range. SC8802 hence is suitable for applications of 1 to 6 series battery modules. The driver voltage is set to 10V to fully utilize external MOSFETs for maximum efficiency.SC8802 supports bi-directional outputs by controlling DIR pin. It supports input current limit, output current limit, dynamic output voltage regulation, internal current limit, output short protection and over temperature protections to ensure safety under different abnormal conditions.SC8802 adopts 32 pin QFN 4x4 package.
