The device enters in shutdown mode when this pin is tied to a high level.

In this case the output is

NCP392D Adjustable Front End Overvoltage Protection Controller with Protected Vbus Output The NCP392D is an overvoltage front end protection controller and is able to disconnect the systems from its output pin in case wrong input operating conditions are detected, up to +28 V.

Thanks to this device using internal NMOS, no external device is necessary, reducing the system cost and the PCB area of the application board.

Internal OVLO threshold is available, or can be adjusted if an external resis
