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 from3V 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/under voltage, system and battery over-voltage protection, MOSFETs over-current protection. Over temperature protection. SC8806 is available in a 4mm x 4mm QFN-32 Package.
