9.1 Application Information

A typical application consists of the device configured as an I2C controlled parallel charger along with a standard switching charger, however, it can also be used with a linear charger or PMIC with integrated charger as well. BQ25960H can start fast charging after the main charger completes pre-charging. BQ25960H will then hand back charging to the main charger when final current tapering is desired. This point is usually where the efficiency of the main charger is acceptable for the application. The device can be used to charge Li-Ion and Li-polymer batteries used in a wide range of smartphones and other portable devices. To take advantage of the high charge current capabilities of the BQ25960H, it may be necessary to charge in excess of 1C. In this case, be sure to follow the battery manufacturers recommendations closely.
