TPS259241DRCT

Current Regulation/Management Overview

The TPS259241DRCT is a single-channel hot-swap voltage controller from Texas Instruments, designed as an electronic fuse (eFuse). It operates within a supply voltage range of 4.5 V to 13.8 V and supports a current limit of 1 A to 5 A. The device features a typical on-resistance of 28 mΩ and consumes 420 µA of quiescent current. It is housed in a 10-pin VSON package and includes a driver for an external blocking FET. The component functions across a temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrates a high-side switch with an integrated circuit driver for an external N-channel blocking FET to prevent reverse current flow.
• Provides comprehensive protection against overcurrent, short circuits, and thermal events through adjustable current limiting and fault detection.

Current Regulation/Management Applications

• Hot-swap insertion protection for peripheral cards and backplane systems
• Power distribution networks requiring isolated channel control
• Input surge protection for sensitive load circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DRCT' corresponds to the cut-tape packaging format required for your assembly line. Confirm that the external blocking FET selection aligns with the internal driver capabilities and system voltage ratings. Ensure the PCB footprint matches the VSON-10 mechanical outline specified in the official datasheet to guarantee proper thermal and electrical performance.

Current Regulation/Management Selection Notes

Select this component when an external blocking FET is preferred for optimized reverse current protection or higher efficiency. Compare the 28 mΩ on-resistance against system power loss requirements. Verify that the 13.8 V maximum input voltage covers the application's peak supply conditions. Consider the 420 µA quiescent current impact on standby power budgets relative to other eFuse options.

Current Regulation/Management Part Context

This part belongs to the TPS25924x series of hot-swap controllers. It shares the VSON-10 package and core protection logic with variants like the TPS259240DRCT, which integrates the blocking FET internally. The TPS259241 variant specifically exposes the driver for external FET integration, offering design flexibility for custom reverse current handling.

Current Regulation/Management Replacement Considerations

The TPS259240DRCT serves as a direct functional substitute if internal blocking FET integration is acceptable. For applications requiring different current limits or voltage ranges, consult the broader TPS2592 family datasheets for compatible alternatives with matching pinouts and protection features.
