概要
説明
The DA9318 is optimized to handle high charging currents and at the same time ensure the safety of the battery and the system. It operates together with a main charger, which handles the pre-charge and constant voltage charging duties.
The current doubling is achieved with a high-efficiency capacitive divider that provides an output voltage of VIN/2, which allows the use of standard USB Type-C™ cables for charging currents up to 6A. The peak efficiency of DA9318 is 98%. With a maximum 8A charging current, the DA9318L variant can provide 35W of charging power, whereas the DA9318M variant provides 10A of output current and 44W of charging power.
