Overview
The TPS16630RGET, produced by Texas Instruments, is a 60-V, 6-A electronic fuse (eFuse) designed for industrial applications. This device is part of the TPS1663x family and provides robust protection for systems powered from 4.5 V to 60 V. It integrates a 60-V, 31-mΩ RON hot-swap FET and offers adjustable current limiting, overvoltage protection, and undervoltage lockout. The TPS16630RGET is particularly useful for hot-pluggable boards, offering features such as in-rush current control and programmable output voltage slew rate. This component is available in a 24-pin VQFN package and is specified over a temperature range of –40°C to +125°C.
