Hot Swap Controllers datasheet and documents for RS31210BR

RS31210BR

Hot Swap Controllers Overview

The RS31210BR is a simple 5V eFuse protection switch manufactured by Reed Semiconductor Corp. It functions as an active circuit protection device with an integrated MOSFET designed to limit current and voltage to safe levels during fault conditions. The component operates within a supply voltage range of 4.5V to 5.5V and supports a maximum output current of 5A. It features an adjustable input UVLO threshold and an adjustable current limit ranging from 2A to 5A. The device utilizes a 10-VFDFN exposed pad package for surface mount mounting and is rated for an operating temperature range of -40°C to 125°C.

Hot Swap Controllers Feature Summary

Integrated 25mΩ pass MOSFET for efficient power handling
Adjustable input under-voltage lockout (UVLO) threshold
Adjustable current limit capability between 2A and 5A
Auto retry functionality for fault recovery

Hot Swap Controllers Applications

Hot swap controller applications
Active circuit protection in 5V systems
Current and voltage limiting during fault conditions

Hot Swap Controllers Procurement Notes

Verify the specific marking code R1210B on the component body to confirm authenticity against the official datasheet specifications. Ensure the ordering suffix BR corresponds to the Tape & Reel packaging format required for your assembly process. Confirm that the 10-VFDFN Exposed Pad package dimensions match your PCB footprint design constraints before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when a dedicated hot swap controller or eFuse solution is required for 5V rail protection. The adjustable current limit allows customization for loads up to 5A, while the integrated MOSFET simplifies board layout compared to discrete solutions. Consider the 10-VFDFN package size and thermal requirements for high-temperature environments up to 125°C.

Hot Swap Controllers Part Context

The RS31210BR belongs to the RS31210/RS31310 family of simple eFuse protection switches from Reed Semiconductor Corp. This series includes variants for different voltage rails, such as the 12V RS31310. These devices are engineered to provide robust protection by integrating control logic and power switching into a single compact surface-mount package.
