Hot-swap controller for -48 V telecom and industrial backplanes
The Texas Instruments TPS2399D is a hot-swap controller IC designed for -48 V power rails, housed in an 8-pin VSSOP package. It manages inrush current and provides overcurrent protection when boards are inserted into a live backplane, a common requirement in telecom central-office and industrial -48 V distributed-power systems.
Active production — no end-of-life concern
The TPS2399D carries an Active lifecycle status, meaning Texas Instruments continues to manufacture and support the part. No last-time-buy or obsolescence notice applies, which simplifies BOM planning for both new designs and ongoing production.
Package and handling for the board shop
The 8-VSSOP package is a standard MSOP-8 footprint, suitable for automated assembly. The Bulk shipping medium means parts arrive in tubes or trays rather than tape-and-reel; plan for manual or tube-fed pick-and-place if the line is set up for reel-only feeders.
