IP5568 supports the external resistor setting of the initial capacity of thebattery, and uses the integration of

the current and time at the port of the battery to manage the remaining capacity of the battery, which can

accurately display the current remaining capacity of the battery.IP5568 supports the automatic calibration of the

total capacity of the current battery in a complete charging process from 0% to 100%, and more reasonable

management of the actual capacity of the battery.

Ip5568 external pin sets the initial cell capacity formula: battery capacity = R8 * 0.2 (mAH). Up to 25000mah.
