NIS5452 Series
+5 Volt Electronic Fuse
The NIS5452 series 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. It also 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
operation. Two thermal options are available, latching and auto−retry.
