TPS259260DRCR

Current Regulation/Management Overview

The TPS259260DRCR is a Hot Swap Voltage Controller manufactured by Texas Instruments, designed for robust power distribution in electronic systems. It operates within an input voltage range of 4.5 V to 13.8 V and supports a maximum supply voltage of 18 V. The device features a low on-resistance of 30 mΩ and provides adjustable current limiting between 2 A and 5 A. Quiescent current consumption is specified at 420 uA. It is housed in a compact VSON-10 surface-mount package and functions reliably across an extended temperature range from -40 °C to +85 °C.

Current Regulation/Management Feature Summary

• Integrates high-side switch with adjustable current limit for precise load protection
• Includes integrated blocking FET driver to prevent reverse current flow
• Provides power fail detection capability for system monitoring

Current Regulation/Management Applications

• Hot swap insertion in backplane systems
• Power distribution units (PDUs)
• Industrial control equipment power inputs
• Telecommunications infrastructure power modules

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DRCR' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and quantity per reel. Ensure that the selected component matches the required thermal performance specifications for the intended operating environment. Cross-reference the part number with the latest product change notifications to confirm availability status and any potential lifecycle changes.

Current Regulation/Management Selection Notes

Select this controller when the application requires a single-channel hot swap solution with an input voltage up to 13.8 V. The 30 mΩ on-resistance makes it suitable for applications prioritizing efficiency over higher current capacities found in other series members. Consider the VSON-10 package size constraints and the need for integrated reverse current protection when evaluating alternative PMIC options.

Current Regulation/Management Part Context

This component belongs to the TPS25926 family of eFuses and hot swap controllers from Texas Instruments. It serves as a specialized power management IC within the broader PMIC category, focusing on safe insertion and removal of circuit boards while protecting downstream loads from overcurrent conditions.

Current Regulation/Management Replacement Considerations

The TPS259250DRCR is a related variant within the same family offering similar current limiting capabilities but may differ in specific threshold configurations or internal resistance characteristics.
