NCP349  
Positive Overvoltage  
Protection Controller with  
Internal Low RON NMOS FET  
The NCP349 is able to disconnect the systems from its output pin  
when wrong input operating conditions are detected. The system is  
positive overvoltage protected up to +28 V.  
http://onsemi.com  
This device uses an internal NMOS and therefore, no external  
device is necessary, reducing the system cost and the PCB area of the  
application board.

The NCP349 is able to instantaneously disconnect the output from  
the input, due to integrated Low R Power NMOS (65 mW), if the  
input voltage exceeds the overvoltage threshold (OVLO) or falls  
below the undervoltage threshold (UVLO).

The NCP349 provides a negative going flag (FLAG) output, which  
alerts the system that a fault has occurred.  
In addition, the device has ESDprotected input (15 kV Air) when  
bypassed with a 1.0 mF or larger capacitor.
