SC89781 is a synchronous buck charger, which supports buck mode and boost mode during forward charging or reverse discharging operations. SC89781 manages 1S to 4S battery charging from a wide input range from 4.5V to 24V and supports automatic system power selection with NMOS drivers on the battery side and adapter side. The device adopts hybrid power boost architecture which allows the battery to work with the adapter to supply the system load when it exceeds the adapter capability in turbo mode. The adapter supplies the system power directly and charges the battery pack with dynamic power management to avoid over-loading. As the system power increases, the charging current will reduce to maintain the adapter current in regulation. If the system power continuously increases and hybrid power boost mode will be triggered to supplement system power. Through the SMBUS interface, the user can set the charging current, charging voltage, input current limit, current limits, switching frequency, and other parameters flexibly. Besides, charging and discharging current also can be set in real-time via the external ILIM pin. SC89781 is compliant with Intel IMVP8/IMVP9 specifications including system power, input current, charging or discharging current monitoring, and processor hot indication. SC89781 can operate in learn mode and ship mode to meet the user’s demands. Full protection is supported including over-temperature protection, adapter, and battery overvoltage protection, input MOSFETs over-current protection, battery, inductor, and MOSFET short circuit protection. SC89781 is available in a 4mm x 4mm QFN-28 Package.
