TPS26600PWPT

Current Regulation/Management Overview

The TPS26600PWPT is a single-channel industrial eFuse from Texas Instruments, housed in a 16-pin HTSSOP package. It operates within a voltage range of 4.2 V to 60 V, with an absolute maximum rating of 62 V. The device integrates back-to-back MOSFETs providing a total on-resistance of 150 mΩ and supports an adjustable current limit between 0.1 A and 2.23 A with ±5% accuracy at 1 A. Quiescent current is 300 µA in operation and 20 µA in shutdown. It features integrated reverse input polarity protection down to –60 V, adjustable UVLO, OVP cutoff, and output slew rate control.

Current Regulation/Management Feature Summary

• Integrated back-to-back MOSFETs provide reverse input polarity protection without additional components.
• Adjustable current limiting with selectable fault response options including auto-retry, latch-off, and circuit breaker modes.
• Includes an Imon current indicator output for monitoring load conditions.
• Supports load protection during surge events with minimal external components.

Current Regulation/Management Applications

• Programmable logic controllers
• Distributed control systems

Current Regulation/Management Procurement Notes

Verify the specific suffix 'PWPT' confirms the tape-and-reel packaging format rather than tube. Confirm the device meets functional safety documentation requirements if applicable to your system design. Ensure the operating temperature range aligns with industrial specifications. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with integrated reverse polarity protection is required. It is suitable for applications needing adjustable current limits and multiple fault response behaviors. Consider the 16-pin HTSSOP package for space-constrained designs requiring thermal performance. Verify that the 60-V input range covers the system's maximum supply voltage.

Current Regulation/Management Part Context

This part belongs to the TPS2660x family of 60-V, 2-A industrial eFuses. It shares core features with variants like TPS26600PWPR and TPS26602, differing primarily in packaging and specific overvoltage clamp configurations. The PWPT suffix indicates a reel-based packaging option for automated assembly processes.

Current Regulation/Management Replacement Considerations

TPS26600PWPR is a direct alternative with identical electrical characteristics but different packaging (reel vs. tube). TPS26602 offers similar functionality with a fixed 38-V overvoltage clamp. TPS26602RHFR provides the same specs in a QFN package.
