TPS26601RHFR

Current Regulation/Management Overview

The TPS26601RHFR is a single-channel industrial eFuse from Texas Instruments, housed in a 24-VQFN 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. Key electrical parameters include a quiescent current of 300 µA in operating mode and 20 µA in shutdown. It features integrated reverse input polarity protection down to –60 V and includes an iMon current indicator output with ±8.5% accuracy.

Current Regulation/Management Feature Summary

• Integrates back-to-back MOSFETs for low on-resistance and built-in reverse input polarity protection without external components
• Provides adjustable current limiting with selectable fault response modes including auto-retry, latch-off, and circuit breaker options
• Includes an iMon current indicator output for real-time load current monitoring
• Features programmable undervoltage lockout, overvoltage cutoff, and output slew rate control

Current Regulation/Management Applications

• Programmable logic controllers
• Distributed control systems
• Industrial power distribution networks

Current Regulation/Management Procurement Notes

Verify the specific suffix RHFR corresponds to the 24-VQFN package and tape-and-reel packaging configuration. Confirm that the component meets functional safety documentation requirements if applicable to your system design. Ensure the ordering part number matches the exact pinout and thermal pad specifications required by your PCB layout.

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 up to 2.23 A and precise current monitoring via the iMon pin. Consider the 24-VQFN package size constraints and thermal dissipation capabilities during the design phase.

Current Regulation/Management Part Context

This device belongs to the TPS2660x family of 60-V, 2-A industrial eFuses. The family shares core functionalities such as integrated MOSFETs and reverse polarity protection but varies in channel count and specific package options. The TPS26601 variant specifically offers a single channel in a compact QFN footprint.

Current Regulation/Management Replacement Considerations

Compatible substitutes within the same family include TPS26600, TPS26602, and TPS26603. Verify package compatibility and pin alignment before substitution. Other variants may offer different channel counts or slight parameter variations.
