The NCP392 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. Thanks to this device using internal NMOS, no external device is necessary, reducing the system cost and the PCB area of the application board.

• Over-voltage Protection Up to + 28V
• On-chip low Rdson NMOS transistors: Typical 34 mΩ
• Fixed and externally adjustable OVLO (6.8 V default)
• + 100 V surge capability, in compliance with IEC61000-4-5 both 1.2/50us and 10/700us
