TPS259533DSGT

Current Regulation/Management Overview

The TPS259533DSGT is a single-channel hot-swap voltage controller and electronic fuse manufactured by Texas Instruments. It operates within an input voltage range of 2.7V to 18V and supports output currents from 0.5A to 4A. The device features a WSON-8 package with dimensions of 2x2 mm, designed for surface mount installation. It functions across a junction temperature range of -40°C to +125°C and includes power fail detection capabilities.

Current Regulation/Management Feature Summary

• Integrates adjustable current limiting and programmable soft-start functionality for controlled power-up sequences.
• Provides comprehensive protection mechanisms including overcurrent, thermal shutdown, and reverse current blocking.
• Features low on-resistance to minimize conduction losses during normal operation.

Current Regulation/Management Applications

• Hot-swap applications in industrial equipment requiring safe insertion and removal under load.
• Power distribution units protecting downstream circuits from short-circuit faults.
• System-level power management in embedded controllers and communication modules.

Current Regulation/Management Procurement Notes

Verify the specific suffix 'GT' indicates tape and reel packaging when ordering. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the 8-WSON footprint matches your PCB layout guidelines before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with integrated eFuse capabilities is required for voltages up to 18V. Consider the 4A maximum current rating and WSON-8 package size relative to available board space. Evaluate the need for external programming components if precise current limit thresholds are necessary for the target application.

Current Regulation/Management Part Context

This part belongs to the TPS2595xx family of hot-swap controllers, which are designed for robust power distribution. The TPS259533 variant specifically denotes the current limit setting and feature set within this series. It serves as a critical interface between the power source and the load, ensuring system reliability.

Current Regulation/Management Replacement Considerations

The TPS259533DSGR is a compatible alternative differing primarily in packaging format (cut tape vs. reel). Verify pinout compatibility and electrical parameters before substitution. No other direct substitutes are confirmed in public documentation.
