TPS259620DDAT

Current Regulation/Management Overview

The TPS259620DDAT is a single-channel hot-swap voltage controller from Texas Instruments designed for robust power distribution. It operates within an input voltage range of 2.7 V to 19 V and supports adjustable current limiting from 125 mA to 2 A. The device features a low on-resistance of 85 mΩ, enabling efficient power delivery with minimal voltage drop. It includes programmable soft-start and fault detection capabilities, ensuring controlled inrush current and protection against overcurrent and thermal events. Operating across a temperature range of -40°C to +125°C, it is housed in an SO-PowerPad-8 package.

Current Regulation/Management Feature Summary

• Integrates high-side N-channel MOSFET control with adjustable current limiting for precise load management
• Provides intelligent inrush current control via programmable soft-start to prevent bus collapse during startup
• Includes comprehensive fault protection mechanisms such as input UVLO, OVP, and thermal shutdown

Current Regulation/Management Applications

• Hot-swap insertion in telecommunications and networking equipment
• Power distribution units requiring controlled power-up sequences
• Industrial systems needing robust overcurrent and thermal protection

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DDAT' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the 85 mΩ RDS(on) and 2 A maximum current limit align with your system's thermal and electrical requirements. Ensure compatibility with the SO-PowerPad-8 footprint during PCB layout. Cross-reference the latest datasheet revision for any updates to pinout or electrical characteristics before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with integrated MOSFET control is required for voltages up to 19 V. It is suitable for applications demanding adjustable current limits between 125 mA and 2 A. Consider its low quiescent current and compact SO-PowerPad-8 package for space-constrained designs. Evaluate the need for programmable fault delays and soft-start timing to match system stability requirements.

Current Regulation/Management Part Context

The TPS259620 belongs to the TPS2596x family of hot-swap controllers from Texas Instruments. This series is engineered for reliable power management in environments where live insertion and removal are common. The device integrates protection features typically found in discrete solutions, simplifying design complexity while enhancing system reliability and performance.

Current Regulation/Management Replacement Considerations

The TPS259620DDAR is the reel-packaged equivalent of the DDAT part number. Verify if the specific reel quantity or handling requirements dictate the choice between DDAT and DDAR variants. No other direct functional substitutes are confirmed in the provided documentation.
