TPS26613DDFR

Current Regulation/Management Overview

The TPS26613DDFR is a 50-V universal current loop protector from Texas Instruments, designed for analog input/output, sensor transmitters, HART inputs, and UART IO protection. It supports ±20 mA, 0–20 mA, and 4–20 mA loops with a low RON of 7.5 Ω to minimize voltage drop. The device withstands ±50 V supply voltages and operates on dual supplies from ±2.25 V to ±20 V or single supplies from 3 V to 30 V. It features a MODE pin for flexible current limiting and includes loop power mode for testing without external power.

Current Regulation/Management Feature Summary

• Provides universal input protection for standard industrial current loops including 4-20 mA and ±20 mA configurations.
• Features low ON-resistance to minimize voltage drop and extend operational range under low supply conditions.
• Includes integrated miswiring protection against input and output errors.
• Supports flexible current limiting via the MODE pin to accommodate two-times current limit requirements.

Current Regulation/Management Applications

• Analog input signal conditioning circuits
• HART protocol communication interfaces
• Sensor transmitter protection
• UART I/O line protection

Current Regulation/Management Procurement Notes

Verify the specific suffix DDFFR indicates the tape-and-reel packaging configuration in the official datasheet. Confirm the operating temperature range matches your system requirements. Ensure the 50-V rating aligns with your maximum supply voltage expectations. Cross-reference the exact part number with the manufacturer's latest documentation to confirm availability and revision status before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when protecting universal current loops requiring robust miswiring defense. It is suitable for applications needing low voltage drop across the protection circuit. Consider its compatibility with both bipolar and unipolar power supplies. Evaluate the need for flexible current limiting capabilities provided by the MODE pin for startup scenarios.

Current Regulation/Management Part Context

This device belongs to the TPS2661x family of current loop protectors. It shares functional similarities with other members like the TPS26610 and TPS26612 but may differ in packaging or specific electrical characteristics. The family is designed for industrial automation and process control environments where reliable signal integrity is critical.

Current Regulation/Management Replacement Considerations

The TPS26610DDFR and TPS26612DDFR are documented as potential substitutes within the same family. Verify pinout compatibility and specific electrical parameters such as RON and voltage ratings before substitution. Consult the official datasheet for detailed comparison tables to ensure functional equivalence in your specific application.
