TPS26600RHFR

Current Regulation/Management Overview

The TPS26600RHFR is a 60-V, 2-A industrial eFuse with integrated reverse input polarity protection. It operates within a 4.2-V to 60-V voltage range and features back-to-back MOSFETs with a total R(on) of 150 mΩ. The device supports an adjustable current limit from 0.1 A to 2.23 A with ±5% accuracy at 1 A. It includes low quiescent current (300 µA operating, 20 µA shutdown), adjustable UVLO/OVP, output slew rate control, and reverse current blocking. Available in a 24-pin VQFN package.

Current Regulation/Management Feature Summary

• Integrated back-to-back MOSFETs providing reverse input polarity protection down to -60 V without additional components
• Adjustable current limiting with selectable fault response options including auto-retry, latch-off, and circuit breaker modes
• Low quiescent current consumption for efficient power management in active and shutdown states
• Programmable output slew rate and overvoltage clamp capabilities for surge protection

Current Regulation/Management Applications

• Programmable logic controllers
• Distributed control systems
• Industrial automation equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix RHFR indicates the 24-pin VQFN package variant. Confirm the device meets functional safety documentation requirements if applicable to your system design. Ensure input voltage ranges align with the 4.2-V to 60-V specification. Check for UL recognition file numbers relevant to your regional compliance standards.

Current Regulation/Management Selection Notes

Select this component when high-side protection with integrated reverse polarity handling is required. The 24-pin VQFN package suits space-constrained layouts. Consider the adjustable current limit range for load matching. Evaluate the need for specific fault response modes like auto-retry versus latch-off based on system recovery requirements.

Current Regulation/Management Part Context

Part of the TPS2660x family of 60-V, 2-A industrial eFuses. Shares core features with TPS26600PWPR but differs in package type. The RHFR suffix specifically denotes the 24-pin VQFN form factor, distinguishing it from HTSSOP variants within the same electrical family.

Current Regulation/Management Replacement Considerations

TPS26600PWPR offers identical electrical specifications in a 16-pin HTSSOP package. Verify pinout compatibility and thermal performance differences between the VQFN and HTSSOP packages before substitution.
