ON Semiconductor NIS6452 Resettable Electronic Fuses are cost-effective fuses that enhance the reliability of a hard drive or any other circuit from catastrophic and shutdown failures. These fuses buffer the load device from the excessive input voltage that can damage the sensitive circuits and protect the input side circuitry from reverse currents. The NIS6452 fuses come with an overvoltage clamp circuit that limits the output voltage during transients. This overvoltage clamp circuit does not shut the unit down and allows the load circuit to continue the operation. The NIS6452 fuses feature digital and tristate enable, integrated soft-start circuit, and an internal charge pump. Typical applications include hard drives, Solid-State Drives (SSDs), and motherboards.
