RS31515 Stackable 60V, 15A eFuse
October 20, 2024
Reed Semiconductor is excited to announce the RS31515, a Stackable 60V, 15A eFuse that combines advanced hot-swap protection, integrated current monitoring, and programmable fault management in a compact 5 mm × 5 mm QFN-30 package. Designed for industrial automation, server infrastructure, networking equipment, and telecommunications systems, the RS31515 simplifies high-current power distribution while providing comprehensive protection against electrical faults.
With an integrated low 7mΩ MOSFET, programmable current limiting, and support for parallel operation, the RS31515 enables designers to build efficient, scalable power systems without compromising reliability or board space.
Advanced Circuit Protection for Modern Power Systems
As system power levels continue to increase, protecting sensitive electronics from overcurrent, short circuits, and voltage transients has become increasingly important. The RS31515 actively monitors load current and limits fault energy before damage can occur, helping improve system reliability while reducing design complexity.
Unlike traditional fuse-based solutions, the RS31515 provides intelligent protection that can be configured to meet the specific requirements of the application. Designers can optimize startup behavior, fault response, and current limits without adding significant external circuitry.
Why Choose a Stackable 60V eFuse?
Wide Operating Range
The RS31515 supports an operating input voltage range from 6V to 60V, making it suitable for a wide variety of industrial and communications power architectures.
High Current Capability
Designed to deliver up to 15A of continuous load current, the device can also be operated in parallel with additional RS31515 stackable 60V eFuses to support even higher-current applications.
Low-Loss Integrated MOSFET
An integrated 7mΩ power MOSFET minimizes conduction losses and improves overall system efficiency while eliminating the need for an external switching device.
Integrated Current Monitoring
A built-in current monitor output provides real-time load current information, allowing system controllers to monitor power consumption, detect abnormal operating conditions, and improve overall system diagnostics.
Programmable System Configuration
The RS31515 provides several programmable features that simplify system optimization, including:
- Adjustable current limit threshold
- Configurable soft-start
- Programmable insertion delay
- Selectable fault recovery modes
These settings allow designers to tailor system behavior for a wide range of power distribution requirements.
Comprehensive Protection Features
Integrated protection functions help safeguard both the power source and downstream circuitry, including:
- Input overvoltage protection
- Adjustable overcurrent protection
- Short-circuit protection
- Overtemperature protection
- FET short detection
- Open-drain FAULT output
- Selectable latch-off or auto-retry fault recovery
Designed for Scalable Power Architectures
One of the RS31515’s key advantages is its stackable architecture. Multiple devices can be connected in parallel to distribute current across multiple power paths, enabling designers to build higher-current systems while maintaining precise protection and monitoring on each channel.
This scalable approach makes the RS31515 particularly attractive for applications requiring modular power expansion or increased redundancy.
Applications
he RS31515 stackable 60V eFuse is well suited for a variety of high-reliability power systems, including:
Industrial Equipment
Protect PLCs, motor controllers, industrial computers, and factory automation equipment from overloads and fault conditions while improving system uptime.
Servers and Data Centers
Provide intelligent hot-swap protection for server power distribution, storage systems, and auxiliary power rails where reliability and current monitoring are essential.
Networking and Telecommunications
Protect switches, routers, communication infrastructure, and telecom equipment with programmable fault management and integrated current monitoring.
Compact Package for High-Density Designs
The RS31515 integrates advanced protection circuitry, current monitoring, and a low-resistance MOSFET into a compact QFN-30 (5 mm × 5 mm) package. This highly integrated solution reduces component count, simplifies PCB layout, and enables higher power density compared to traditional discrete implementations.
