TPS259240DRCR

Current Regulation/Management Overview

The TPS259240DRCR is a single-channel hot-swap voltage controller from Texas Instruments, designed as an eFuse for circuit protection. It operates within a supply voltage range of 4.5 V to 13.8 V and supports load currents from 1 A to 5 A. The device features a low on-resistance of 28 mΩ, minimizing power loss during conduction. It includes integrated power fail detection and is housed in a compact VSON-10 package suitable for surface-mount applications.

Current Regulation/Management Feature Summary

• Integrates high-side switch with adjustable current limiting for precise overcurrent protection
• Includes built-in power fail detection to monitor input voltage integrity
• Features low on-resistance for efficient power delivery and reduced thermal stress

Current Regulation/Management Applications

• Hot-swap insertion protection for backplane and midplane systems
• Circuit protection in industrial control and automation equipment
• Power distribution units requiring single-channel load switching

Current Regulation/Management Procurement Notes

Verify the specific suffix DRCR against the manufacturer datasheet to confirm tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the VSON-10 footprint dimensions with your PCB design guidelines to guarantee mechanical compatibility and proper thermal dissipation characteristics.

Current Regulation/Management Selection Notes

Select this model when a single-channel solution with up to 5 A capacity is required. The 4.5 V to 13.8 V input range suits standard 5 V and 12 V systems. Consider the 28 mΩ resistance for efficiency needs. Compare against other series variants if higher voltage tolerance or external FET driver integration is necessary for your specific topology.

Current Regulation/Management Part Context

This component belongs to the TPS25924 series of integrated eFuses. It consolidates switch, control, and protection functions into a small form factor. The series targets applications needing reliable hot-swap capabilities without discrete component complexity. It serves as a direct replacement for traditional fuse and discrete MOSFET arrangements in modern power management designs.
