TPS26400PWPR

Current Regulation/Management Overview

The TPS26400PWPR is a single-channel industrial eFuse and hot-swap voltage controller manufactured by Texas Instruments. It supports an input voltage range from 4.2 V to 42 V and provides programmable current limiting between 100 mA and 2.23 A. The device operates with a quiescent current of 300 uA and functions within a temperature range of -40°C to +125°C. It utilizes a 16-pin HTSSOP package for surface mount installation.

Current Regulation/Management Feature Summary

• Integrates reverse input polarity protection to prevent damage from incorrect power connections.
• Provides programmable soft-start functionality to control inrush current during startup.
• Features adjustable current limit settings for flexible load protection configurations.

Current Regulation/Management Applications

• Industrial system bus protection
• Hot-swappable peripheral interface circuits
• Voltage regulation for high-side loads

Current Regulation/Management Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and thermal characteristics. Ensure compatibility with the target PCB footprint and soldering profile. Confirm that the component meets all required environmental standards for the intended deployment environment before finalizing procurement decisions.

Current Regulation/Management Selection Notes

Select this component when designing systems requiring robust overcurrent protection and controlled power-up sequences. It is suitable for applications needing isolation between power sources and sensitive downstream loads. Consider the thermal performance of the HTSSOP package relative to the expected continuous load current.
