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.

Features

• Integrated Power Device

• Power Device Thermally Protected

• No External Current Shunt Required

• 40 mW Typical

• Internal Charge Pump

• Internal Undervoltage Lockout Circuit

• Internal Overvoltage Clamp

• ESD Ratings: Human Body Model (HBM); 2000 V

Machine Model (MM); 200 V

• These are Pb−Free Devices and are RoHS Compliant

Typical Applications

• Mother Board

• Hard Drives

• Fan Drives
