onsemi NCP349
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.| Part No. | NCP349 |
