NCP81428

NCP81428 is a PMBus® enabled, 12V, 50A resettable in-line fuse designed for comprehensive protection against overcurrent events, overvoltage events, short circuit events, and excessive inrush current. The NCP81428 consists of a 0.65mohm NMOS FET, a high performance hot-swap controller, and a non-volatile memory (NVM). The NCP81428 can be configured as a single-phase solution, or in multi-phase as a host or a server to support higher current applications. Typically used in servers, data storage, base stations, industrial applications.
