Electronic eFuse
Description
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.
Features
• 42 mW Typical • Digital and Tristate Enable • Integrated Reverse Current Protection • Thermally Protected • Integrated Soft−Start Circuit • Fast Response Overvoltage Clamp Circuit • Internal Undervoltage Lockout Circuit • Internal Charge Pump • Load Current Monitor Pin • ESD Ratings: Human Body Model (HBM); 2000 V
