SC8806 is a synchronous buck-boost charger, which
supports buck mode, boost mode and buck-boost mode
during forward charging or reverse discharging operation.
SC8806 manages 1 to 4 cells battery charging from wide
input range from 3.5V to 26V, supporting pre-charge,
constant current charge, constant voltage charge. The
battery discharging mode supports wide output range from
3V to 20.8V with 8mV resolution. SC8806 is compliant with
Intel IMVP8/IMVP9 specification including system power,
input current, charging or discharging current monitoring.
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.
SC8806 supports pass through mode to reduce switching
losses during forward charging. 10-bit ADC is integrated to
monitor voltage, current and power. SC8806 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.
SC8806 is available in a 4mm x 4mm QFN-28 Package
