The ON Semiconductor series NCP81292 is a 50 A, electronically re−settable, in−line fuses for use in 12 V, high current applications such as servers, storage and base stations. The NCP81292 offers a very low 0.65 mΩ integrated MOSFET to reduce solution size and minimize power loss. It also integrates a highly accurate current sensor for monitoring and overload protection.
