Overview
The TPS16632RGER from Texas Instruments is a 60-V, 6-A electronic fuse (eFuse) designed for robust protection and power management in various industrial and consumer applications. This device operates within a voltage range of 4.5 V to 60 V, with an absolute maximum voltage of 67 V, making it suitable for systems powered from industrial SELV power supplies. The TPS16632RGER integrates a 31-mΩ hot-swap FET and offers adjustable current limiting, overvoltage protection, and undervoltage lockout features. It is particularly useful for hot-pluggable boards, providing in-rush current control and programmable output voltage slew rate. The device is available in a 4-mm × 4-mm 24-pin VQFN package and is specified over a temperature range of –40°C to +125°C.
