TITPS25940ARVCR
Overview
The TPS25940ARVCR is a highly integrated circuit protection and power management device that functions as an electronic fuse and power mux controller. Operating from 2.7V to 18V, it provides robust protection against overvoltage, overcurrent, and reverse current while supporting up to 5.3A of continuous output current. This eFuse is UL 2367 recognized and designed for high-density power management in enterprise systems and storage applications.
Why Choose This Part
This eFuse offers high-precision current limiting (+/-8% accuracy) and integrated reverse current blocking, which eliminates the need for external blocking diodes. Its low on-resistance and small 3mm x 4mm WQFN package minimize power loss and PCB footprint, while the programmable dv/dt control manages inrush current during startup.
Applications
Key Specifications
Getting Started
Evaluation can be performed using the TPS25940EVM development board to test adjustable current limits and dv/dt settings. Engineers should select the RILIM resistor value carefully to set the desired current limit and use the EN/UVLO pin to program the undervoltage lockout threshold. The device provides both FLT and PG open-drain outputs for real-time monitoring by a system microcontroller.
