RS31311BR

Hot Swap Controllers Overview

The RS31311BR is an electronic fuse integrated circuit manufactured by Reed Semiconductor Corp. It functions as a power distribution switch with a maximum output current of 4A and operates within an input voltage range of 2.7V to 18V. The device features a current limit accuracy of ±7.5% and is housed in an 8-WSON (2x2) package with exposed pad. It supports surface mount installation and operates across a junction temperature range of -40°C to 125°C.

Hot Swap Controllers Feature Summary

• Integrated electronic fuse protection for load circuits
• Precision current limiting capability
• Compact surface-mount packaging design

Hot Swap Controllers Applications

• General-purpose power distribution switching
• Overcurrent protection in embedded systems
• Load management in industrial control units

Hot Swap Controllers Procurement Notes

Verify the specific manufacturer datasheet for the RS31311BR to confirm pinout compatibility and electrical ratings against your system requirements. Ensure that the thermal performance of the 8-WSON package meets your application's heat dissipation needs under maximum load conditions. Cross-reference the component specifications with your board layout guidelines to ensure proper grounding and trace sizing for the 4A current capacity.

Hot Swap Controllers Selection Notes

Select this component when a compact, single-channel electronic fuse solution is required for low-voltage applications up to 18V. Consider the 8-WSON footprint if space constraints are critical. Evaluate the ±7.5% current limit tolerance to ensure it aligns with the protection thresholds of the downstream loads. Verify that the operating temperature range covers the environmental conditions of the intended deployment site.

Hot Swap Controllers Part Context

This component belongs to the class of electronic fuses and power switches designed for protecting sensitive electronics from overcurrent events. Unlike traditional fuses, these ICs offer resettable protection and precise current limiting. They are commonly used in modern portable devices and industrial equipment where reliable power management and compact form factors are essential for system integration and safety compliance.
