5 A Fully Integrated Li-Ion Switching Battery Charger with Power Path Management and USB On-The-Go Support
The NCP1854 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 NCP1854 junction temperature is monitored during charge cycle and both current and
voltage can be modified accordingly through I2C...
