TPS25942ARVCT

Current Regulation/Management Overview

The TPS25942ARVCT is a single-channel hot-swap voltage controller and eFuse power multiplexer from Texas Instruments. It operates within an input voltage range of 2.7 V to 18 V and supports current limits adjustable from 600 mA to 5.3 A. The device features a low quiescent supply current of 210 uA and includes power failure detection capabilities. It is housed in a WQFN-20 package suitable for surface mount technology and functions reliably across an operating temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Integrates hot-swap control with eFuse power multiplexing functionality for robust power distribution management.
• Provides configurable current limiting to protect downstream loads from overcurrent conditions.
• Includes dedicated power failure detection circuitry to monitor system integrity.

Current Regulation/Management Applications

• Industrial equipment requiring reliable hot-plug capability
• Telecommunications infrastructure power systems
• Embedded systems needing protected power multiplexing

Current Regulation/Management Procurement Notes

Verify the specific suffix 'RVCT' confirms the cut tape packaging variant rather than reel stock. Confirm the 'A' grade designation aligns with required operational specifications. Ensure the WQFN-20 footprint matches the target PCB layout constraints. Validate that the 2.7 V to 18 V input range satisfies the system's voltage requirements.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution combining hot-swap protection and power multiplexing is required. The wide input voltage range suits various industrial standards. Consider the WQFN-20 package size for space-constrained designs. Verify that the adjustable current limit range covers the maximum load requirements without unnecessary derating.

Current Regulation/Management Part Context

This part belongs to the TPS25942A family of hot-swap controllers. It serves as a specialized power management integrated circuit designed for high-reliability applications. The device integrates protection features typically found in discrete solutions into a compact monolithic structure, simplifying board design and improving overall system efficiency.

Current Regulation/Management Replacement Considerations

The TPS25942ARVCR is the identical functional component packaged on a reel instead of cut tape. Other members of the TPS25942A series may offer different pinouts or feature sets; verify datasheet compatibility before substitution.
