TPS259271DRCR

Current Regulation/Management Overview

The TPS259271DRCR is a hot-swap voltage controller from Texas Instruments, functioning as an eFuse with an integrated back-to-back FET driver for reverse current protection. It operates within a supply voltage range of 4.5 V to 18 V and supports a continuous load current up to 5 A. The device features a low on-resistance of 28 mΩ and draws a typical operating supply current of 420 µA. Designed for surface-mount installation, it is housed in a compact VSON-10 package and functions reliably across an industrial temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrates a back-to-back FET driver to enable bidirectional current flow control and reverse current protection.
• Provides power-fail detection capabilities to monitor system status during fault conditions.
• Supports hot-swap operations allowing safe insertion and removal of boards under power.

Current Regulation/Management Applications

• Hot-swap circuit protection for peripheral cards and backplanes
• Power distribution units requiring reverse current blocking
• Industrial equipment input power protection

Current Regulation/Management Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and functional configuration. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the VSON-10 package dimensions align with your PCB footprint design. Check for moisture sensitivity level ratings to determine proper storage and reflow soldering procedures.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with integrated reverse current protection is required. The 28 mΩ on-resistance offers efficiency benefits over discrete solutions. Consider the 4.5 V minimum operating voltage to ensure compatibility with your system's power rails. The VSON-10 package provides a compact form factor suitable for space-constrained designs.

Current Regulation/Management Part Context

This part belongs to the TPS25927 series of hot-swap controllers. It is distinct from variants like the TPS259261 or TPS259250 by its specific integration of the back-to-back FET driver for reverse current protection. The DRCR suffix indicates the tape-and-reel packaging format for automated assembly.
