NIS5232 +12 Volt Electronic Fuse

Pin Function Description 1 Ground Negative input voltage to the device. This is used as the internal reference for the IC. 2 dv/dt The internal dv/dt circuit controls the slew rate of the output voltage at turn on. It has an internal capacitor that allows it to ramp up over a period of 2 m.

+12 Volt Electronic Fuse NIS5232 Series The NIS5232 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.
