NCP81428中文资料Hot Swap Smart Fuse, 18 V, 0.65 mΩ, 50 A, LQFN32数据手册ONSEMI规格书

描述 Description

The NCP81428 is a PMBus® enabled, 12 V, 50 A resettable in-line fuse designed for comprehensive protection against over current events, over voltage events, short circuit events, and excessive inrush current. The NCP81428 consists of a 0.65 mΩ NMOS FET, a high performance Hot-Swap Controller, and a Non-Volatile Memory (NVM) all co-packaged into a LQFN32 package. The NCP81428 can be configured as a single-phase solution, or in multi-phase as a Master or a Slave to support higher current applications.
