TPS25944ARVCT

Current Regulation/Management Overview

The TPS25944ARVCT is a single-channel hot-swap voltage controller and eFuse from Texas Instruments, housed in a 20-pin WQFN package. It supports an input voltage range of 2.7 V to 18 V with a maximum continuous current limit adjustable between 600 mA and 5.3 A. The device features a low quiescent operating current of 210 uA and operates within a temperature range of -40°C to +125°C. Designed for PCI power management, it integrates power failure detection and reverse current protection capabilities.

Current Regulation/Management Feature Summary

• Integrated eFuse functionality providing precise current limiting and thermal protection
• Supports hot-swap operations with controlled turn-on slew rate
• Includes integrated reverse current protection to prevent backflow
• Features DevSleep support for system power state management

Current Regulation/Management Applications

• PCI/PCIe peripheral power management
• Industrial equipment input power distribution
• Telecommunications infrastructure power systems
• Server and storage backplane power routing

Current Regulation/Management Procurement Notes

Verify the specific suffix 'RVCT' corresponds to the required tape-and-reel packaging configuration and temperature grade. Confirm that the 20-pin WQFN footprint matches the target PCB layout. Ensure compatibility with the intended input voltage range up to 18 V before finalizing procurement specifications.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with high voltage tolerance up to 18 V is required. It is suitable for applications needing adjustable current limits up to 5.3 A and integrated reverse current protection. Consider the WQFN-20 package size for space-constrained designs requiring surface-mount installation.

Current Regulation/Management Part Context

This device belongs to the TPS25944A series of hot-swap controllers. It serves as a robust power distribution element within Texas Instruments' portfolio of power management ICs. The part is designed to protect downstream circuits from overcurrent and short-circuit conditions while enabling safe insertion and removal of powered modules.

Current Regulation/Management Replacement Considerations

The TPS25940ARVCR is a related variant within the same family offering similar eFuse functionality. Verify pinout compatibility and specific current limit ranges when considering substitutes. Ensure the replacement part meets the required operating temperature and voltage specifications.
