Hot Swap Smart Fuse NCP81295, NCP81296 The NCP81295 and NCP81296 are 50 A, electronically resettable, inline fuses for use in 12 V, high current applications such as servers, storage and base stations. The NCP81295/6 offers a very low 0.65 m integrated MOSFET to reduce solution size and minimize power loss. It also integrates a highly accurate current sensor for monitoring and www.onsemi.com overload protection.
