TPS26602RHFR

Current Regulation/Management Overview

The TPS26602RHFR is a single-channel hot-swap voltage controller manufactured by Texas Instruments, designed for robust power distribution management. It operates within an input voltage range of 4.2 V to 55 V and supports output currents up to 2.35 A. The device features a low on-resistance of 150 mΩ and consumes only 300 µA of quiescent current during operation. Packaged in a 24-VQFN (5x4 mm) format with an exposed thermal pad, it ensures efficient heat dissipation. The component functions as an electronic fuse, providing precise current limiting and protection against fault conditions across a wide industrial temperature range from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrates high-side N-channel MOSFET control with built-in current limiting and thermal shutdown for comprehensive circuit protection.
• Provides programmable soft-start capabilities to manage inrush current and prevent voltage droop during system startup.
• Features remote enable functionality allowing for flexible system-level power sequencing and control logic integration.

Current Regulation/Management Applications

• Industrial automation systems requiring reliable power bus protection
• Telecommunications infrastructure equipment needing hot-swappable power modules
• Automotive electronics demanding high-voltage tolerance and rugged operation

Current Regulation/Management Procurement Notes

Verify the specific suffix RHFR confirms the 24-VQFN package and tape-and-reel packaging configuration. Ensure compatibility with your PCB footprint dimensions and thermal pad requirements. Confirm that the 4.2 V minimum operating voltage aligns with your system's supply rails. Validate that the 150 mΩ on-resistance meets your efficiency and voltage drop specifications under maximum load conditions.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with moderate current capacity is required. The 150 mΩ resistance offers a balance between conduction loss and cost compared to lower-resistance alternatives. Consider the 24-VQFN package if space constraints allow for its larger footprint but require superior thermal performance. Evaluate the 300 µA quiescent current impact on standby power budgets in battery-operated or energy-efficient designs.

Current Regulation/Management Part Context

This part belongs to the TPS2660x family of hot-swap controllers, which are engineered for protecting power buses in various electronic systems. The TPS26602 variant specifically targets applications requiring single-channel protection with integrated MOSFET drive capabilities. It complements other devices in the series like the TPS26600 and TPS26601, offering distinct pinout and feature sets tailored to different design needs.

Current Regulation/Management Replacement Considerations

Direct substitutes include TPS26602PWPR and TPS26602RHFT, which share identical electrical characteristics but differ in package type or reel quantity. Verify pin-to-pin compatibility before substitution. Alternative families may require external MOSFETs and additional support components, increasing design complexity.
