NCP349 28V Overvoltage Protection

Pin No. Symbol Function Description 1, 7 IN INPUT Input Voltage Pins. These pins are connected to the Wall Adapoter (AC *DC, Vbus ..). A 1 mF low ESR ceramic capacitor, or larger, must be connected between these pins and GND, as close as possible to the DUT. The two IN pins must be connecte.
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.
