SC8804
High Efficiency, Synchronous, Bi directional Boost Charger Controller
Introduce
 

SC8804 is a synchronous boost charger controller. It is able to effectively manage charging when input voltage is lower than battery voltage. In charging mode, SC8804 supports trickle charging, constant current (CC) charging and constant voltage (CV) charging management functions automatically. SC8804 supports very wide input and output voltage range. It is suitable for applications of 1 to 6 series battery. The driver voltage is set to 10V to fully utilize external MOSFETs for maximum efficiency. SC8804 also supports reverse buck discharging by controlling DIR pin. Under reverse buck mode, SC8804 outputs a lower VBUS voltage from VBAT. It also supports input current limit, output current limit, dynamic output voltage regulation, internal current limit, and over temperature protections to ensure safety under different abnormal conditions. SC8804 adopts 32 pin QFN 4x4 package.
