TPS26400RHFR

Current Regulation/Management Overview

The TPS26400RHFR is a single-channel hot-swap voltage controller from Texas Instruments, designed as an industrial eFuse. It operates within a supply voltage range of 4.2 V to 42 V and supports a current limit adjustable from 100 mA to 2.23 A. The device features a low quiescent current of 300 uA and is housed in a 24-pin VQFN package. It functions reliably across an extended temperature range of -40°C to +125°C, providing robust power management and circuit protection for high-side N-channel MOSFET applications.

Current Regulation/Management Feature Summary

• Integrates intelligent control for high-side N-channel MOSFETs with near-constant output voltage rise time to manage inrush current.
• Provides comprehensive fault detection including input undervoltage lockout, programmable overvoltage protection, and configurable delay times for various fault conditions.
• Supports remote on/off control via the enable input and latches off during persistent faults until reset.

Current Regulation/Management Applications

• Industrial equipment power distribution
• Telecommunications infrastructure systems
• Automotive electronics modules

Current Regulation/Management Procurement Notes

Verify that the specific RHFR suffix corresponds to the reel packaging configuration required for your assembly line. Confirm that the component meets RoHS standards and humidity sensitivity level requirements for your manufacturing process. Ensure compatibility with the intended MOSFET gate drive characteristics and thermal dissipation capabilities of the target PCB layout.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with adjustable current limiting up to 2.23 A is required. It is suitable for applications needing precise inrush current control and robust fault protection in industrial or automotive environments. Consider the VQFN-24 package size and operating temperature range against board space and environmental constraints.

Current Regulation/Management Part Context

This part belongs to the TPS2640 series of hot-swap controllers. It serves as a specialized power management IC within the broader PMIC category, focusing on protecting downstream loads from power supply anomalies. It complements other Texas Instruments solutions by offering integrated eFuse functionality without requiring external complex protection circuits.
