NCP349GEVB:POSITIVE OVP EVB
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 Low RON Power NMOS (65 mΩ), if the input voltage exceeds the overvoltage threshold (OVLO) or falls below the undervoltage threshold (UVLO). The NCP349 provides a negative going flag (FLAG) output, which alerts the system that a fault has occurred. In addition, the device has ESD-protected input (15 kV Air) when bypassed with a 1.0 µF or larger capacitor.
