Electronic Fuse, +3.3/+5 Volt
NIS6432, NIS6452
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.
