TPS25940ARVCR

Current Regulation/Management Overview

The TPS25940ARVCR is a single-channel hot-swap voltage controller and electronic fuse from Texas Instruments, housed in a 20-WQFN package. It supports an input voltage range of 2.7 V to 18 V with a typical on-resistance of 42 mΩ and a current limit adjustable between 600 mA and 5.3 A. The device features integrated reverse current protection, DevSleep support, and power fail detection. Operating temperatures span from -40°C to +85°C, with a quiescent current of 202 µA.

Current Regulation/Management Feature Summary

• Integrated true reverse blocking capability prevents backflow current without external components.
• DevSleep support enables low-power standby modes for portable applications.
• Adjustable current limit allows precise load protection configuration.
• Power fail detection provides system status monitoring during fault conditions.

Current Regulation/Management Applications

• Hot-swap insertion for peripheral cards and backplanes
• Point-of-load power distribution protection
• Battery backup switchover circuits
• Portable equipment power management

Current Regulation/Management Procurement Notes

Verify the specific suffix 'RVCR' confirms the standard commercial grade temperature range and reel packaging. Confirm RoHS compliance and lead-free status against the latest manufacturer datasheet. Ensure ESD handling protocols are followed due to the exposed thermal pad design. Cross-reference the Mouser number 595-TPS25940ARVCR for accurate distributor identification.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with integrated reverse blocking is required. The 42 mΩ on-resistance suits moderate current applications up to 5.3 A. Consider the 20-WQFN package for space-constrained designs requiring thermal performance. Verify that the 2.7 V minimum input voltage aligns with the source supply characteristics.

Current Regulation/Management Part Context

This part belongs to the TPS25940 family of eFuses, designed for robust power distribution. It complements other TI hot-swap controllers by offering simplified implementation through integrated protection features. The RVCR variant specifically denotes the tape-and-reel packaging format suitable for automated surface-mount assembly processes.
