TPS26602PWPR

Current Regulation/Management Overview

The TPS26602PWPR is a single-channel industrial eFuse from Texas Instruments, housed in a 16-pin HTSSOP package. It operates within a voltage range of 4.2 V to 60 V, with an absolute maximum rating of 62 V. The device integrates back-to-back MOSFETs providing a total on-resistance of 150 mΩ and supports an adjustable current limit between 0.1 A and 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, reverse current blocking, and selectable fault response modes including auto-retry, latch-off, and circuit breaker.

Current Regulation/Management Feature Summary

• Integrated reverse input polarity protection down to -60 V without additional components
• Adjustable current limiting with selectable fault response options for system flexibility
• Fixed 38 V overvoltage clamp for enhanced load protection
• IMON current indicator output for real-time status monitoring

Current Regulation/Management Applications

• Programmable logic controllers
• Distributed control systems

Current Regulation/Management Procurement Notes

Verify the specific suffix 'PWPR' confirms the 16-pin HTSSOP package and tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the functional safety documentation is available if your design requires IEC 61508 or ISO 26262 certification support. Validate that the thermal performance of the HTSSOP package aligns with your system's power dissipation constraints under maximum load conditions.

Current Regulation/Management Selection Notes

Select this part when integrated reverse polarity protection and a fixed 38 V overvoltage clamp are required. The TPS26602 differs from the TPS26600 by including the fixed clamp feature. Choose this device for applications needing adjustable current limits up to 2.23 A with precise accuracy. Consider the 16-pin HTSSOP package for space-constrained designs requiring surface-mount integration.

Current Regulation/Management Part Context

The TPS26602 belongs to the TPS2660x family of industrial eFuses designed for robust power management. This series provides comprehensive protection against surge events, short circuits, and overcurrent conditions. The device simplifies system design by integrating high-side switching capabilities and eliminating the need for external discrete components typically required for similar protection functions.

Current Regulation/Management Replacement Considerations

The TPS26600PWPR serves as a direct substitute if the fixed 38 V overvoltage clamp is not required. Both devices share identical pinouts, packages, and core protection features. Verify that the absence of the fixed clamp in the replacement does not violate system voltage tolerance specifications.
