TPS26631PWPT

Current Regulation/Management Overview

The TPS26631PWPT is a positive 60-V, 6-A electronic fuse (eFuse) from the Texas Instruments TPS2663 family. It integrates a 31-mΩ hot-swap FET and features adjustable output power limiting (PLIM), making it suitable for industrial applications requiring IEC61000-4-5 surge protection and IEC61010-1 compliance. The device supports an operating voltage range of 4.5 V to 60 V with an absolute maximum rating of 67 V. It offers adjustable current limits from 0.6 A to 6 A and includes fast reverse current blocking capabilities. Packaged in a 20-pin HTSSOP, it operates within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrates a 60-V, 31-mΩ hot-swap FET for efficient power control
• Features adjustable output power limiting (PLIM) for system protection
• Supports external N-channel FET control via B-FET driver for reverse polarity and current blocking
• Provides selectable overcurrent fault responses including auto-retry and latch-off modes

Current Regulation/Management Applications

• Programmable Logic Controllers (PLC)
• Distributed Control Systems (DCS)
• Human-Machine Interface (HMI) modules
• Industrial sensor hubs
• CNC motor drives

Current Regulation/Management Procurement Notes

Verify the specific suffix 'PWPT' corresponds to the 20-pin HTSSOP package variant when ordering. Confirm that the required functionality matches the TPS26631 sub-family, which lacks certain advanced variants found in other TPS2663x models. Ensure compatibility with the target PCB footprint and thermal requirements for the HTSSOP enclosure before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component for systems requiring robust industrial-grade surge protection and precise power limiting. The TPS26631 variant specifically supports adjustable current limits and PLIM, distinguishing it from basic eFuses. Consider the 20-pin HTSSOP package if board space allows for its larger footprint compared to QFN options. Verify that the 6-A continuous current rating meets the load requirements without exceeding thermal limits.

Current Regulation/Management Part Context

The TPS26631PWPT belongs to the TPS2663 series of industrial eFuses designed for high-voltage, high-current DC power rail protection. This series addresses the need for reliable hot-swap capabilities and fault management in harsh industrial environments. The TPS26631 model specifically provides the core protection features with adjustable parameters, serving as a key solution for modernizing legacy industrial control systems.

Current Regulation/Management Replacement Considerations

Direct substitutes include other TPS2663x variants such as TPS26631PWPR or TPS26631PWPGG, depending on the required packaging format. Cross-reference pinouts and electrical specifications carefully, as differences in overvoltage clamp voltages or pulse support may exist between sub-models.
