TPS259803ONRGER

Overview

The TPS259803ONRGER is a hot-swap voltage controller manufactured by Texas Instruments, designed for single-channel power distribution. It operates within an input voltage range of 2.7V to 24V and supports a continuous output current up to 8A. The device features a low on-resistance of 3mΩ, minimizing conduction losses. It is housed in a 24-VFQFN package with exposed pad, suitable for surface mount applications. The component functions as a smart eFuse, providing comprehensive protection against overcurrent, short circuits, and thermal anomalies.

Feature Summary

• Integrates a high-side N-channel MOSFET switch with programmable current limiting and fault protection logic.
• Provides precise control over inrush current and output voltage slew rate during startup sequences.
• Includes built-in power-fail detection and adjustable fault timeout timers for robust system management.

Applications

• Industrial equipment power distribution modules
• Telecommunications infrastructure board-level protection
• General-purpose hot-swap server backplanes

Procurement Notes

Verify the specific suffix 'ONRGER' matches the required tape-and-reel packaging configuration from the manufacturer's official documentation. Confirm that the 24-VFQFN footprint aligns with the target PCB layout. Ensure compliance with RoHS3 standards if required by the end application. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement orders.

Selection Notes

Select this component when a single-channel solution with 8A capacity and 3mΩ resistance is required. It is appropriate for systems needing integrated inrush control and programmable fault handling without external discrete components. Consider the 24-VFQFN package size constraints and thermal dissipation requirements relative to the expected load profile and ambient operating conditions.
