    SC8803 is a synchronous buck charger controller. It is able to
    effectively manage charging when input voltage is higher than
    battery voltage. In charging mode, SC8803 supports trickle
    charging, constant current (CC) charging and constant
    voltage (CV) charging management functions automatically.
    SC8803 supports very wide input and output voltage range. It
    is suitable for applications of 1 to 4 series battery. The driver
    voltage is set to 10V to fully utilize external MOSFETs for
    maximum efficiency.
    SC8803 supports bi-directional outputs by controlling DIR pin.
    Under discharging mode, SC8803 can output a boosted
    voltage from battery to VBUS. 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.
    SC8803 adopts 32 pin QFN 4x4 package
    MPQ:3000
    移动电源/ USB Hub  /智能USB插座/USB电源传输/车充/工业应用

    SC8803是一个同步4管双向升降压充放电控制器。不管输入电压是低于，高于或者等于电池组电压，它都可以对电池组实现充电管理
