# TPS25940LRVCR (Component)
## Description
Electronic Fuse Regulator 5.3A 20-WQFN (3x4)
The TPS25940 is a compact, feature-rich eFuse (electronic fuse) power switch from Texas Instruments designed to provide advanced power-path protection and management for SSDs, storage systems, servers, telecom equipment, and other DC-powered applications. It integrates back-to-back MOSFETs for true reverse-current blocking, programmable current limiting, overvoltage/undervoltage protection, and controlled output slew-rate management in a small 20-pin WQFN package.
Key Features
Wide operating voltage range: 2.7 V to 18 V (20 V maximum input)
Low 42 mΩ typical on-resistance (RDS(on))
Adjustable current limit from 0.6 A to 5.3 A
True reverse-current blocking using integrated back-to-back FETs
Fast reverse-voltage shutdown response of 1 µs
Programmable output ramp-up (dV/dt control) for inrush-current management
Programmable overvoltage (OVP) and undervoltage (UVP) protection thresholds
Integrated IMON analog current-monitor output
PGOOD and FLT status outputs for system monitoring
Low-power DevSleep™ mode for SATA SSD applications
Typical operating quiescent current of 200 µA
Typical disabled current of 15 µA
Operating junction temperature range from −40°C to +125°C
UL 2367 recognized and designed for fault-safe operation under single-point failure conditions.
Typical Applications
PCIe, SATA, and SAS SSD/HDD storage devices
Enterprise servers and storage systems
RAID controller cards with holdup-power management
Telecom switches and routers
Set-top boxes, DTVs, and gaming consoles
Adapter-powered equipment
General-purpose smart load-switch and power-protection circuits.
Package Information
Package: 20-pin WQFN (RVC)
Temperature range: −40°C to +85°C ambient operation
Tape-and-reel packaging for automated assembly.
