TPS259270DRCT

Current Regulation/Management Overview

The TPS259270DRCT is a hot-swap voltage controller from Texas Instruments, functioning as an eFuse with integrated digital authority (DA). It supports input voltages from 4.5 V to 18 V and provides adjustable current limiting between 1 A and 5 A. The device features a low on-resistance of 28 mΩ and operates within a temperature range of -40°C to +85°C. Quiescent current is specified at 420 µA. It utilizes a VSON-10 surface-mount package.

Current Regulation/Management Feature Summary

• Integrates digital authority for programmable control of power-up sequencing and fault handling
• Provides precise current limiting with adjustable thresholds via digital interface
• Includes built-in power-fail detection for system monitoring

Current Regulation/Management Applications

• Hot-swap backplane applications requiring controlled power insertion
• System protection in industrial equipment with 12 V or 24 V buses
• Data center infrastructure managing high-current load switching

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DRCT' corresponds to the cut-tape packaging format required for your assembly line. Confirm that the digital authority interface compatibility matches your microcontroller or FPGA logic levels. Ensure the thermal performance of the VSON-10 package meets your PCB layout constraints under maximum load conditions.

Current Regulation/Management Selection Notes

Select this component when a 18 V maximum input rating is required alongside a 5 A current limit capability. The integrated digital authority distinguishes it from standard eFuses by allowing remote configuration. Consider the 28 mΩ on-resistance for efficiency calculations against alternative devices with higher RDS(on) values.

Current Regulation/Management Part Context

This part belongs to the TPS2592x family of hot-swap controllers designed for robust power distribution. It complements other variants like the TPS259240 and TPS259261 by offering a wider input voltage range up to 18 V. The family shares common digital control features but varies in voltage ratings and current limits.

Current Regulation/Management Replacement Considerations

The TPS259271DRCT serves as a direct functional substitute within the same series, maintaining identical electrical characteristics and pinout compatibility.
