    SC8886S is a synchronous buck-boost charger, which
    supports buck mode, boost mode and buck-boost mode
    during forward charging or reverse discharging operation.
    SC8886S manages 1 to 4 cells battery charging from wide
    input range from 3.5V to 24V, supporting pre-charge,
    constant current charge, constant voltage charge. The
    battery discharging mode supports wide output range from
    3V to 24V with 8mV resolution. SC8886S is compliant with
    Intel IMVP8/IMVP9 specification including system power,
    input current, charging or discharging current monitoring
    and processor hot indication. SC8886S adopts Narrow-VDC
    power path management, which automatically regulates the
    current and voltage and controls the flow of power.
    Through I2C interface, user can set the
    charging/discharging mode easily, and program the
    charging current, charging voltage, VINREG voltage, input
    current limit, reverse output voltage adjustment, current
    limits, switching frequency and other parameters flexibly.
    Besides, input current limit, charge voltage could be set by
    external resistors.
    SC8886S supports pass through mode to reduce switching
    losses during forward charging. The device also supports
    Vmin active mode to absorb system peak power when only
    battery powers the system. 10-bit ADC is integrated to
    monitor voltage, current and power. SC8886S can operate
    in learn mode and ship mode to meet the user’s demands.
    Full protection is supported including input over voltage
    protection/undervoltage, system and battery over-voltage
    protection, MOSFETs over-current protection. overtemperature
    protection.
    SC8886S is available in a 4mm x 4mm QFN-32 Package.
