+5 Volt Electronic eFuse
Description
+5 Volt Electronic eFuse
NIS6351
The NIS6351 is a cost effective, resettable fuse which can greatly enhance the reliability of a USB application 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
• 85 mW Max RDS(on) • Integrated Reverse Current Protection • Adjustable Output Current Limit Protection with Thermal Shutdown • IEC61000−4−2 Level 4 ESD Protection for Vbus up to ±7 kV • Fast Response Overvoltage Clamp Circuit with Selectable Level • Internal Undervoltage Lockout Circuit • Digital Enable with Separate FLAG for Fault Identification • Integrated Current Monitoring • Both Latching and Auto−Retry Options Available • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
Typical Applications
• Automotive Infotainment • USB 2.
