2 System Overview

The TIDA-050090 reference design features a 54V, 5kW input power path protection system in data center servers, utilizing six TPS1685 eFuse devices or one TPS1689 and five TPS1685 eFuse devices arranged in parallel. The TPS1685 and TPS1689 eFuses are compact, package-integrated, parallelizable designs for high-current circuit protection and power management. The devices offer multiple protection modes with minimal external components. The eFuses provide robust defense against overloads, short circuits, and excessive inrush current. This reference design demonstrates the performance of the TPS1685 and TPS1689 eFuses when multiple devices are in parallel to support a higher load current.
