Pin Name Type Description A1 IN A2 IN POWER POWER Battery Charger Input. These two pins must be decoupled by at least 1 mF capacitor and connected together. A3 SPM A4 SDA A5 SCL DIGITAL INPUT DIGITAL BIDIRECTIONAL DIGITAL INPUT System Power Monitor input. I2C data line I2C clock line B1 CAP B2 CAP POWER POWER CAP pin is the intermediate power sup.
under software supervisibon. An optional battery FET can be placed between the system and the battery in order to isolate and supply the system. The NCP1855 junction temperature is 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 NCP1855 also provides USB OTG support by boosting the battery voltage as well as providing overvoltage protected power supply for USB transceiver.
