TPS259250DRCR

Current Regulation/Management Overview

The TPS259250DRCR is a hot-swap voltage controller from Texas Instruments, functioning as an electronic fuse (eFuse). It supports input voltages from 4.5 V to 18 V with a minimum operating voltage of 4.5 V. The device provides a maximum current limit of 5 A and features a typical on-resistance of 30 mΩ. Quiescent current is specified at 420 µA. It operates within a temperature range of -40°C to +85°C and is housed in a VSON-10 package.

Current Regulation/Management Feature Summary

• Integrates adjustable current limiting with accurate threshold control for precise load protection.
• Provides power-fail detection capabilities to monitor system integrity during fault conditions.
• Features low on-resistance to minimize conduction losses and improve efficiency in power delivery.

Current Regulation/Management Applications

• Hot-swap applications requiring controlled insertion into live backplanes
• Power distribution units needing individual channel protection
• System boards requiring eFuse functionality for overcurrent safeguarding

Current Regulation/Management Procurement Notes

Verify the specific suffix 'CR' indicates reel packaging when ordering. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the VSON-10 footprint matches your PCB layout requirements. Check for moisture sensitivity level ratings if reflow soldering is planned. Validate that the 5 A current rating aligns with your thermal management design constraints.

Current Regulation/Management Selection Notes

Select this component when a single-channel hot-swap solution with adjustable current limits is required. Compare against the TPS259251 variant if different pinout or feature sets are needed. Consider the 30 mΩ on-resistance for thermal performance analysis. Evaluate the 420 µA quiescent current impact on standby power budgets. Ensure the 18 V maximum input voltage covers your system's peak supply levels.

Current Regulation/Management Part Context

This part belongs to the TPS25925 series of hot-swap controllers designed for robust power management. It serves as a critical interface between the power source and the load, offering integrated protection features. The series is categorized under PMICs and Controllers & Switches within Texas Instruments' portfolio.

Current Regulation/Management Replacement Considerations

TPS259250DRCT is a tape-and-reel alternative with identical electrical specifications but different packaging format. TPS259250DRCRG4 is a lead-free version of the same device. Verify package compatibility and ordering suffix differences before substitution.
