TPS259271DRCT

Current Regulation/Management Overview

The TPS259271DRCT is a hot-swap voltage controller and electronic fuse (eFuse) manufactured by Texas Instruments. It operates within an input voltage range of 4.5 V to 18 V and supports a continuous current limit of 5 A. The device features a low on-resistance of 28 mΩ and includes an integrated N-channel power FET driver for reverse current protection. 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 a high-side switch with an internal N-channel MOSFET and dedicated gate driver circuitry.
• Provides active reverse current protection to prevent back-feeding into the upstream power source.
• Includes built-in power-fail detection capabilities to monitor output voltage integrity.

Current Regulation/Management Applications

• Hot-swap insertion in server blade chassis
• Industrial equipment power distribution modules
• Telecommunications infrastructure power systems

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DRCT' confirms the cut-tape packaging format upon ordering. Confirm that the 18 V maximum rating aligns with the system's peak bus voltage. Ensure the thermal design accommodates the VSON-10 package constraints under full load conditions.

Current Regulation/Management Selection Notes

Select this component when an 18 V input rail requires robust reverse current blocking alongside standard eFuse protection. The 28 mΩ resistance offers a balance between conduction loss and cost compared to lower resistance alternatives. Verify compatibility with the target PCB footprint for the VSON-10 package.

Current Regulation/Management Part Context

This part belongs to the TPS2592x family of hot-swap controllers from Texas Instruments. These devices are designed for applications requiring safe insertion and removal of live circuits while providing comprehensive overcurrent and short-circuit protection.

Current Regulation/Management Replacement Considerations

The TPS259270DRCT is a confirmed substitute within the same series, offering identical electrical characteristics and pinout compatibility for direct replacement in existing designs.
