STEF05DPUR Electronic Fuse from STMicroelectronics

The STEF05DPUR is a state-of-the-art electronic fuse designed by STMicroelectronics, tailored to provide overcurrent protection in a wide range of applications. It is a part of STMicroelectronics' eFuses, which are electronic fuses that protect power lines by limiting the current that can pass through them when a fault condition occurs.

Key Features

• Current Rating: The device supports a continuous current of up to 0.5 A, making it suitable for low-power applications.
• Operating Voltage: It operates over a wide input voltage range from 4.5 V to 18 V, accommodating various power supply standards.
• Adjustable Overcurrent Protection: Users can set the overcurrent threshold through an external resistor, providing flexibility in different circuit designs.
• Fast Trip Time: The STEF05DPUR reacts swiftly to fault conditions, ensuring that the circuit is protected quickly to prevent damage.
• Auto-Retry Feature: After a fault condition, the device will automatically attempt to reset itself, which can be useful in transient fault scenarios.
• Thermal Protection: The built-in thermal shutdown mechanism protects against overheating, which enhances the safety and longevity of both the eFuse and the protected circuit.

Applications

The STEF05DPUR is versatile and can be used in a variety of applications, including:

• Consumer Electronics
• Industrial Systems
• Computing and Storage Systems
• Power Supply Modules

Package and Availability

This electronic fuse is available in a small and reliable 8-lead DFN package (3x3 mm), which is ideal for space-constrained applications. The STEF05DPUR is also characterized by its low R<sub>DS(on), which ensures minimal power loss during operation, making it an energy-efficient solution for modern electronic devices.
