TPS25942LRVCR

Current Regulation/Management Overview

The TPS25942LRVCR is a hot-swap voltage controller and eFuse power mux manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 18 V and supports a continuous output current up to 5 A. The device features adjustable current limiting with a range from 600 mA to 5.3 A and maintains high accuracy of ±8%. Designed for surface-mount installation, it utilizes a 20-WQFN package with exposed thermal pad. The component ensures reliable operation across an extended junction temperature range of -40°C to +125°C while consuming only 210 µA of quiescent supply current.

Current Regulation/Management Feature Summary

• Integrated reverse current protection prevents backflow from load to source.
• Configurable soft-start controls inrush current during power-up sequences.
• Built-in power limit detection monitors system health under fault conditions.

Current Regulation/Management Applications

• Server blade power distribution
• Industrial I/O module protection
• Telecommunications equipment power management

Current Regulation/Management Procurement Notes

Verify the specific suffix 'L' confirms the commercial temperature grade (-40°C to +85°C) rather than the industrial grade. Confirm the 'RVCR' suffix indicates the 20-WQFN package type and reel packaging format. Ensure compatibility with the target PCB footprint and thermal design requirements before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when bidirectional current flow must be prevented in single-supply systems. The adjustable current limit allows customization for various load profiles. Verify that the required operating voltage falls strictly within the 2.7 V to 18 V window. Consider the 20-WQFN package size constraints against available board space and thermal dissipation capabilities.

Current Regulation/Management Part Context

This part belongs to the TPS2594x family of eFuses designed for robust power path management. It serves as a critical interface between the main power rail and sensitive downstream loads. The device integrates high-side switching capabilities with comprehensive diagnostic features for modern embedded systems requiring precise power control.
