TPS259472ARPWR

Current Regulation/Management Overview

The TPS259472ARPWR is a single-channel hot-swap voltage controller from Texas Instruments, designed for robust power distribution in industrial and computing systems. It operates within an input voltage range of 2.7 V to 23 V and supports load currents up to 5.5 A. The device features a typical on-resistance of 28 mΩ, ensuring efficient power delivery with minimal loss. Integrated protection mechanisms include adjustable current limiting, thermal shutdown, and reverse current blocking. It is housed in a compact VQFN-10-HR (2x2 mm) package suitable for surface-mount applications.

Current Regulation/Management Feature Summary

• Integrated eFuse architecture combining high-side switching with comprehensive fault protection
• Adjustable current limit and soft-start control for precise power-up sequencing
• Reverse current blocking capability to prevent backflow during system faults
• Thermal shutdown and overcurrent protection for enhanced system reliability

Current Regulation/Management Applications

• Hot-swap power distribution in server and storage backplanes
• Industrial equipment requiring safe insertion and removal under load
• Peripheral expansion slots in computing systems
• Power management units in telecom infrastructure

Current Regulation/Management Procurement Notes

Verify the complete part number including suffixes such as 'A' for temperature grade and 'PWR' for package type against official Texas Instruments documentation. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure compatibility with your board's thermal design and footprint requirements for the VQFN-10-HR package.

Current Regulation/Management Selection Notes

Select this component when designing systems that require safe hot-plugging capabilities with integrated current limiting. The 28 mΩ on-resistance offers a balance between conduction loss and cost compared to lower resistance alternatives. Consider the 2.7 V minimum operating voltage for compatibility with standard logic levels and ensure adequate thermal dissipation for the VQFN-10-HR package in enclosed environments.

Current Regulation/Management Part Context

This device belongs to the TPS25947 family of hot-swap controllers, which are engineered for high-reliability power distribution. The family provides configurable protection thresholds and integrates gate drive circuitry for external or internal MOSFETs. The TPS259472 variant specifically targets applications needing moderate current handling with built-in safety features, distinguishing it from simpler switches or higher-current industrial controllers.

Current Regulation/Management Replacement Considerations

Consult Texas Instruments datasheets for direct pin-compatible alternatives within the TPS2594x series. Verify electrical parameters such as on-resistance and current limits before substituting. No public confirmed substitute part numbers are listed in available documentation.
