TPS2590RSAT

Overview

The TPS2590RSAT is a hot-swap controller manufactured by Texas Instruments, designed for general-purpose applications. It operates within a supply voltage range of 3V to 20V and supports output currents up to 5A. The device features an internal switch and is housed in a 16-VQFN package with a bare pad (4x4 mm). Key electrical parameters include a minimum operating temperature of -40°C and a maximum of 125°C. It offers programmable current limit and slew rate capabilities, along with thermal limiting and UVLO features.

Feature Summary

• Integrates an internal high-side switch for simplified circuit design
• Provides programmable current limiting and adjustable slew rate control
• Includes thermal limiting and under-voltage lockout protection mechanisms

Applications

• General-purpose hot-swap control
• System board insertion protection
• Backplane power management

Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to ensure correct packaging and tape/reel specifications. Confirm that the selected variant matches the required pin configuration and thermal performance for your specific PCB layout. Cross-reference the datasheet revision history to account for any updates in electrical characteristics or recommended operating conditions prior to final procurement.

Selection Notes

Select this component when designing systems requiring controlled power-up sequences and fault protection during board insertion. Ensure the external components align with the internal switch ratings and that the thermal dissipation requirements are met within the specified operating temperature range. Verify compatibility with the system's input voltage levels and load characteristics before integration.

Part Context

The TPS2590 belongs to the TPS2590/10 family of hot-swap controllers from Texas Instruments. These devices are engineered to manage the inrush current and protect against overcurrent conditions during system board insertion. The RSAT suffix indicates a specific tape and reel packaging option suitable for automated assembly processes in high-volume manufacturing environments.

Replacement Considerations

Direct substitutes may include other members of the TPS2590 family with compatible pinouts and electrical specifications. Verify functional equivalence regarding current limits, voltage ranges, and package dimensions before substitution.
