TPS25940ARVCT

Current Regulation/Management Overview

The TPS25940ARVCT is a hot-swap voltage controller manufactured by Texas Instruments, designed for robust power distribution in electronic systems. It operates within an input voltage range of 2.7 V to 18 V and supports continuous load currents up to 5 A. The device features a low on-resistance of 42 mΩ, minimizing conduction losses during operation. Integrated reverse current protection prevents backflow from the output to the input. The component is housed in a 20-WQFN package and functions reliably across an extended temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrated true reverse current blocking capability
• Supports DeviceSleep mode for power management
• Built-in thermal shutdown protection

Current Regulation/Management Applications

• Hot-swap circuit protection
• Voltage bus distribution
• System power sequencing

Current Regulation/Management Procurement Notes

Verify the ordering suffix 'CT' corresponds to cut-tape packaging rather than reel packaging when sourcing components. Confirm that the specific variant matches the required package type and tape-and-reel specifications for automated assembly processes. Ensure compatibility with standard surface-mount placement equipment.

Current Regulation/Management Selection Notes

Select this component for applications requiring high-current hot-swap capabilities with integrated reverse blocking. The 20-WQFN package offers a compact footprint suitable for space-constrained designs. Consider the 42 mΩ on-resistance for efficiency calculations and verify that the 5 A current limit aligns with system load requirements.

Current Regulation/Management Part Context

This part belongs to the TPS25940 family of eFuses and hot-swap controllers. It provides comprehensive protection features including overcurrent, overvoltage, and thermal safeguards. The device simplifies power distribution design by integrating control logic and power switches into a single solution.
