Overview

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.
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 RON Power NMOS (65 mW), if the input voltage exceeds the overvoltage threshold (OVLO) or falls below the undervoltage threshold (UVLO).
At powerup (EN pin = low level), the Vout turns on ton time...
