TPS259525DSGT

Current Regulation/Management Overview

The TPS259525DSGT is a 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 current limit up to 4 A. The device features a low on-resistance of 34 mΩ, minimizing power loss during operation. Designed for surface-mount installation, it utilizes an 8-pin WSON package with dimensions of 2x2 mm. The component functions as a single-channel power switch suitable for PCI power management applications. It provides comprehensive protection against overcurrent and thermal events while ensuring safe insertion and removal of hot-pluggable boards.

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DSGT' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the 8-WSON package footprint matches the target PCB layout design. Ensure the application voltage does not exceed the 18 V maximum rating. Check for any required external components such as gate resistors or soft-start capacitors as specified in the official datasheet. Validate compliance with RoHS directives for environmental standards.

Current Regulation/Management Selection Notes

Select this component for applications requiring robust hot-swap protection with high current capacity. Consider the 34 mΩ on-resistance for efficiency requirements in power-sensitive designs. Evaluate the 2.7 V minimum operating voltage against system standby rails. Compare the 4 A current limit against peak load demands to ensure adequate headroom. Assess the WSON-8 package size constraints relative to available board space.
