MARKING

The NCP1850 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. The device

integrates a synchronous PWM controller, power MOSFETs, and the

entire charge cycle monitoring including safety 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 NCP1850 junction temperature and battery temperature are

monitored during charge cycle, and both current and voltage can be

modified accordingly through I C setting. The charger activity and

status are reported through a dedicated pin to the system. The input pin

is protected against overvoltages.

The NCP1850 also provides USB OTG support by boosting the

battery voltage as well as providing overvoltage protected power

supply for USB transceiver.
