TPS25910RSAR

Overview

The TPS25910RSAR is a hot-swap controller manufactured by Texas Instruments, designed for general-purpose applications. It features an internal power switch capable of handling up to 5A output current and operates within a supply voltage range of 3V to 20V. The device supports adjustable current limiting and slew rate control to manage inrush currents during board insertion. It is housed in a 16-QFN (4x4) package with exposed pad, suitable for surface-mount installation. The component functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates a high-side N-channel MOSFET with programmable current limit and voltage slew rate control
• Provides comprehensive protection including under-voltage lockout, thermal shutdown, and over-current protection
• Supports remote on/off control via enable input for system power management flexibility

Applications

• Industrial equipment backplane power distribution
• Telecommunications infrastructure card insertion
• General-purpose hot-swap power control systems

Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration when ordering. Confirm that the 16-QFN package dimensions match the target PCB footprint. Ensure the input voltage range aligns with the system's available rail voltages before finalizing procurement specifications.

Selection Notes

Select this component when active board insertion protection is required without external discrete switches. Consider the internal switch current rating against peak load requirements. Evaluate the need for programmable slew rates to minimize bus disturbance during hot-plug events compared to fixed-rate alternatives.

Part Context

This part belongs to the TPS25910 family of hot-swap controllers, which are engineered for robust power distribution in environments requiring frequent maintenance or module replacement. The series offers integrated protection features typically found in discrete solutions, simplifying design complexity while ensuring reliable operation in demanding industrial and telecom settings.
