NCP367  
Battery Charge Front-End  
Protection, USB and AC/DC  
Supply Compliant  
NCP367 is a charge path protection device which allows  
disconnecting the systems from its output pin in case wrong charging  
conditions are detected. The system is positive overvoltage protected  
up to +30 V. Thanks to a very low current consumption, the USB  
charge is compatible with this integrated component.

This device uses internal PMOS FET, making external devices  
unnecessary, which reduces the system cost and PCB area of the  
application board. First, NCP367 is able to instantaneously  
disconnect the output from the input if the input voltage exceeds the  
overvoltage threshold. Additional overcurrent protection function  
allows turning off internal PMOS FET when the charge current  
exceeds current limit, which is externally selectable.

MARKING DIAGRAM  
The current limit value can be modified with control logic pin to  
divide it by internal gain, allowing USB 100 mA/500 mA charging or  
USB/Wall adapter charging up to overcurrent threshold. At the same  
time, Li ion Battery voltage is continuously monitored, providing  
more safety during the charge. Thermal shutdown protection is also  
available.  
NCP367 provides a negative going flag (FLAG) output, which  
alerts the system that a fault has occurred as overvoltage (power  
supply or battery voltage), overcurrent or thermal event.
