TPS2421-1DDA

Hot Swap Controllers Overview

The TPS2421-1DDA is a hot-swap voltage controller from Texas Instruments featuring an integrated power FET. It supports input voltages from 3 V to 20 V and provides a current limit of 5 A. The device operates within a temperature range of -40°C to +125°C and utilizes an 8-SO-PowerPad package. Key electrical parameters include a maximum supply voltage of 20 V, minimum supply voltage of 3 V, and quiescent current of 6 mA.

Hot Swap Controllers Feature Summary

• Integrates a high-side N-channel MOSFET for compact board space
• Provides programmable soft-start and current limiting
• Includes automatic retry functionality upon fault clearance

Hot Swap Controllers Applications

• Server backplane power distribution
• Industrial control system inputs
• Telecommunications equipment protection

Hot Swap Controllers Procurement Notes

Verify the exact suffix against official documentation, as 'DDA' may denote specific tape-and-reel or packaging variations distinct from standard 'DDAR'. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the supplier source aligns with Texas Instruments authorized channels to guarantee component authenticity and traceability.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution with integrated switching capability is required. Consider the 5 A current rating and 20 V input window for suitability in mid-power applications. Evaluate thermal performance requirements relative to the SO-PowerPad package's heat dissipation capabilities under expected load conditions.

Hot Swap Controllers Part Context

This part belongs to the TPS2421 series of hot-swap controllers designed for protecting downstream circuits during insertion or removal. It simplifies design by combining control logic with the power switch, eliminating external gate drive components typically needed in discrete solutions.
