The NIS64x2 is a cost effective, resettable fuse which can greatly

enhance the reliability of a hard drive or other circuit from both

catastrophic and shutdown failures.

It is designed to buffer the load device from excessive input voltage

which can damage sensitive circuits and to protect the input side

circuitry from reverse currents. It includes an overvoltage clamp

circuit that limits the output voltage during transients but does not shut

the unit down, thereby allowing the load circuit to continue its

operation.
