The NIS5431 series is a cost effective, resettable fuse which cangreatly enhance the reliability of a hard drive or other circuit from bothcatastrophic and shutdown failures.It is designed to buffer the load device from excessive input voltagewhich can damage sensitive circuits. It also includes an overvoltageclamp circuit that limits the output voltage during transients but doesnot shut the unit down, thereby allowing the load circuit to continueoperation.
