TPS259261DRCR

Current Regulation/Management Overview

The TPS259261DRCR is a hot-swap voltage controller from Texas Instruments, designed as an eFuse for single-channel power distribution. It operates within an input voltage range of 4.5 V to 13.8 V and supports load currents up to 5 A. The device features a typical on-resistance of 30 mΩ and draws a quiescent current of 420 µA. It is housed in a compact 10-pin VSON package and functions reliably across an operating temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrates adjustable current limiting with accurate threshold control for precise overcurrent protection.
• Includes dedicated driver circuitry to manage external blocking FETs for enhanced reverse current isolation.
• Provides comprehensive fault monitoring including power fail detection and thermal shutdown capabilities.

Current Regulation/Management Applications

• Hot-swap insertion in high-density server backplanes
• Industrial equipment requiring robust power distribution switching
• Telecommunications infrastructure power modules

Current Regulation/Management Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout and functional variations. Ensure the component matches the required voltage and current specifications for your target application. Cross-reference datasheet revisions to validate parameter consistency before finalizing procurement decisions.

Current Regulation/Management Selection Notes

Select this component when designing systems requiring controlled hot-plug capabilities with integrated reverse current protection. The built-in driver for external blocking FETs simplifies layout compared to discrete solutions. Evaluate the 30 mΩ on-resistance against thermal dissipation requirements for the maximum expected load current.

Current Regulation/Management Part Context

This part belongs to the TPS25926 series of hot-swap controllers. It shares the VSON-10 footprint with other variants in the family but differs in internal driver configurations and voltage ranges. It serves as a specialized solution for applications needing isolated reverse current protection alongside standard eFuse functionality.

Current Regulation/Management Replacement Considerations

Consult the official TI selection guide for direct pin-to-pin alternatives within the TPS2592x family. Verify that substitute parts support the same 13.8 V maximum input and 5 A current limits. Confirm compatibility with existing PCB layouts and thermal management designs before substitution.
