    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
    MPQ:3000
