NCP1851A Datasheet Fully Integrated Li-ion Switching Battery Charger

Manufacturer: onsemi

Overview: NCP1851, NCP1851A Fully Integrated Li-Ion Switching Battery Charger with Power Path Management and USB On-The-Go Support The NCP1851 is a fully programmable single cell Lithium−ion switching battery charger optimized for charging from a USB compliant input supply and AC adaptor power source.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key Features

  • 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.
