Descriptions

The SC89780 is a synchronous buck charger that supports buck and boost modes during forward or reverse discharging operations. It 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 and adapter sides.

The device adopts hybrid power boost architecture, allowing the battery to work with the adapter to supply the system load when it exceeds the adapter capability in turbo mode. The adapter provides 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. The hybrid power boost mode will be triggered to supplement system power if the system power continuously increases.

The user can flexibly set the charging current, charging voltage, input current limit, discharge current limits, switching frequency, and other parameters flexibly through the SMBUS interface. Besides, charging and discharging current also can be set in real-time via the external ILIM pin.

The SC89780 complies with Intel IMVP8/IMVP9 specifications, including system power, input current, charging or discharging current monitoring, and processor hot indication.

The SC89780 can operate in learn and ship modes to meet the user&＃39;s demands. Full protection includes over-temperature protection, adapter, and battery over-voltage protection, input MOSFETs over-current protection, battery, inductor, and MOSFET short circuit protection.

The SC89780 is available in a 4mm x 4mm QFN-28 Package.
