NCP1852, NCP1852A  
Fully Integrated Li-Ion  
Switching Battery Charger  
with Power Path  
Management and USB  
On-The-Go Support  
http://onsemi.com  
The NCP1852 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 NCP1852 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 NCP1852 also provides USB OTG support by boosting the  
battery voltage as well as providing overvoltage protected power  
supply for USB transceiver.
