NCP391 Overview
NCP391 Positive Overvoltage Protection Controller with Internal Low RON NMOS FET The NCP391 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 NCP391 is able to instantaneously...
