NIS5431 +3.3 Volt Electronic Fuse

GND Pin Function Description 1 *5 Source This pin is the source of the internal power FET and the output terminal of the fuse. 7 ILimit A resistor between this pin and the source pin sets the overload and short circuit current limit levels. 8 Enable/Fault The enable/fault pin is a .

NIS5431 Series +3.3 Volt Electronic Fuse The NIS5431 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 o.
