TPS26602RHFT

Current Regulation/Management Overview

The TPS26602RHFT is a single-channel hot-swap voltage controller from the TPS2660x series, manufactured by Texas Instruments. It operates within an input voltage range of 4.2 V to 60 V, with a maximum absolute rating of 62 V. The device integrates back-to-back MOSFETs providing a total on-resistance (R_ON) of 150 mΩ and supports an adjustable current limit ranging from 0.1 A to 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 a fixed 38 V overvoltage clamp and is housed in a 24-pin VQFN package.

Current Regulation/Management Feature Summary

• Integrated reverse input polarity protection down to -60 V without additional components
• Adjustable UVLO, OVP cutoff, and output slew rate control for surge protection
• Selectable current-limiting fault response options including auto-retry, latch-off, and circuit breaker modes
• IMON current indicator output with ±8.5% accuracy

Current Regulation/Management Applications

• Programmable logic controllers
• Distributed control systems

Current Regulation/Management Procurement Notes

Verify the specific suffix RHFT corresponds to the 24-pin VQFN package and reel quantity of 250 units. Confirm RoHS compliance status and functional safety documentation availability if required for industrial applications. Ensure the fixed 38 V overvoltage clamp characteristic aligns with system design requirements, as this feature is specific to the TPS26602 variant within the family.

Current Regulation/Management Selection Notes

Select the TPS26602RHFT when a fixed 38 V overvoltage clamp is required, distinguishing it from other variants in the TPS2660x series that may lack this feature. Choose the 24-pin VQFN package for compact designs requiring integrated back-to-back MOSFETs. Consider the adjustable current limit range and selectable fault responses for flexible load protection strategies in industrial environments.

Current Regulation/Management Part Context

This component belongs to the TPS2660x series of 60-V, 2-A industrial eFuses. The series is designed for robust load protection with integrated power switches. The TPS26602 variant specifically includes a fixed overvoltage clamp, offering enhanced protection against transient voltage spikes compared to standard eFuse implementations.

Current Regulation/Management Replacement Considerations

TPS26602PWPT: Alternative package option using 16-pin HTSSOP instead of 24-pin VQFN. TPS26602RHFR: Same VQFN package but different reel quantity configuration.
