Battery Charger Input.

These two pins must be decoupled by at least 1 mF capacitor and connected together.

System Power Monitor input.

under software supervision. An optional battery FET can be placed between the system and the battery in order to isolate and supply the system. The NCP1851 junction temperature and battery temperature are monitored during charge cycle, and both current and voltage can be modified accordingly through I2C setting. The charger activity and status are reported through a dedicated pin to the system. The input pin is protected against overvoltages. The NCP1851 also provides USB OTG support by boosting.
