TPS26631PWPR

Current Regulation/Management Overview

The TPS26631PWPR is a single-channel hot-swap voltage controller from the Texas Instruments TPS2663 series, housed in a 20-pin HTSSOP package. It operates within an input voltage range of 4.5 V to 60 V and supports load currents up to 6 A with an on-resistance of 31 mΩ. The device features adjustable current limiting from 0.6 A to 6 A and includes power limiting capabilities. It functions as an industrial eFuse with integrated protection against overcurrent, short circuits, and reverse current.

Current Regulation/Management Feature Summary

• Integrated 60-V, 31-mΩ hot-swap FET for efficient power path management
• Adjustable output power limiting (PLIM) to simplify compliance with safety standards
• Configurable fault response modes including latch-off and auto-retry via MODE pin
• Fast reverse current blocking capability to prevent backflow during system faults

Current Regulation/Management Applications

• Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS)
• Human-Machine Interfaces (HMI) and I/O module power distribution
• CNC machine tool power rail protection
• Industrial sensor hubs requiring surge immunity

Current Regulation/Management Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-20 package and tape-and-reel quantity when ordering. Confirm that the design requires the specific 31 mΩ Ron characteristics and 6 A current handling limits defined in the datasheet. Ensure compatibility with the 4.5 V to 60 V operating range for your target application voltage rails.

Current Regulation/Management Selection Notes

Select this component when high-side protection with precise power limiting is required for industrial systems. It is suitable for applications needing configurable fault responses and robust surge immunity per IEC 61000-4-5. Consider alternative packages like RGER if a smaller footprint is needed, or variants without PLIM if power limiting is not required.

Current Regulation/Management Part Context

This part belongs to the TPS2663x family of industrial electronic fuses designed by Texas Instruments. The family provides comprehensive protection for high-voltage DC systems, integrating control logic with power MOSFETs to manage inrush current and isolate faults. It serves as a replacement for discrete protection circuits in complex power distribution architectures.

Current Regulation/Management Replacement Considerations

Check TPS26631PWPT for the same functionality in a TSSOP package. Verify TPS26631RGER for a QFN package option with similar electrical specifications.
