TPS259520DSGT

Current Regulation/Management Overview

The TPS259520DSGT is a single-channel hot-swap voltage controller and electronic fuse (eFuse) manufactured by Texas Instruments. It operates within an input voltage range of 2.7 V to 18 V and supports a continuous load current of up to 4 A. The device features a typical on-resistance of 34 mΩ, minimizing conduction losses during normal operation. It is housed in an 8-pin WSON package with dimensions of 2 mm x 2 mm, designed for surface-mount installation. The component includes integrated protection mechanisms such as fast overvoltage protection and adjustable current limiting.

Current Regulation/Management Feature Summary

• Integrates fast overvoltage protection to safeguard downstream loads from input transients.
• Provides precise current limiting with adjustable thresholds for flexible system protection.
• Features low on-resistance to maximize efficiency in power distribution networks.

Current Regulation/Management Applications

• Hot-swap applications requiring safe insertion and removal under load
• Point-of-load power distribution systems
• Protection circuits for industrial and communication equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DSGT' against the official Texas Instruments datasheet to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure the ordering part number matches the required quantity per reel specifications. Cross-reference the manufacturer's latest product change notifications to confirm assembly site and material compliance status prior to procurement.

Current Regulation/Management Selection Notes

Select this component when designing systems requiring robust protection against overvoltage and overcurrent conditions within a 2.7 V to 18 V input range. The 4 A current rating and 34 mΩ on-resistance make it suitable for high-efficiency power distribution. Consider the 8-WSON package size for space-constrained PCB layouts. Ensure thermal management strategies align with the device's junction temperature ratings under maximum load conditions.

Current Regulation/Management Part Context

The TPS259520DSGT belongs to the TPS2595x family of eFuses from Texas Instruments. This series is engineered for high-performance power management, offering integrated solutions for load switching and circuit protection.
