NCP392B Adjustable Front End Overvoltage Protection Controller with Protected Vbus Output The NCP392B is an overvoltage front end protection and be able to disconnect the systems from its output pin in case wrong input operating conditions are detected, up to +28 V. Due 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 external resistor bridge is use.
