TPS259621DDAR

Current Regulation/Management Overview

The TPS259621DDAR is a hot-swap voltage controller and eFuse from Texas Instruments, designed for single-channel power distribution. It operates within an input voltage range of 2.7 V to 19 V and supports load currents from 0.13 A to 2 A. The device features an on-resistance of 85 mΩ and includes an accurate current monitor with fast overvoltage protection. It utilizes an SO-PowerPad-8 package and functions across a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrates precise current monitoring capabilities for accurate load measurement
• Provides rapid response to overvoltage events to protect downstream circuitry
• Supports controlled inrush current management during initial startup

Current Regulation/Management Applications

• Server and storage backplane power distribution

Current Regulation/Management Procurement Notes

Verify the specific suffix DDAR against official Texas Instruments documentation to confirm the reel packaging configuration. Ensure that the selected component matches the required thermal performance and electrical ratings for the target application environment. Cross-reference the datasheet revision history to confirm compatibility with existing design specifications.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with integrated current sensing is required. Consider the 85 mΩ on-resistance for efficiency calculations and verify that the 2 A maximum current limit aligns with system load requirements. Evaluate the SO-PowerPad-8 package for thermal dissipation needs in the specific PCB layout.

Current Regulation/Management Part Context

This part belongs to the TPS2596 family of eFuses, which are engineered for high-reliability power management applications. The series emphasizes compact integration of protection and control features, allowing designers to replace discrete MOSFETs and gate drivers with a single managed switch solution.

Current Regulation/Management Replacement Considerations

Direct substitutes include the TPS259621DDA and TPS259621DDAT. Verify pinout compatibility and thermal characteristics before substitution.
