This reference design illustrates a 12V, 4kW input power path protection system for data center servers, using six TPS25985 eFuse devices in parallel. The TPS25985x is a compact, package-integrated, parallelizable, high-current circuit protection and power management device. The primary goal of this reference design is to demonstrate the thermal performance of the TPS25985 eFuse when two devices are positioned in the same area: one at the top and another at the bottom of the PCB. In this configuration, four devices are located on the top layer, while the other two are placed on the bottom layer, directly aligning with the second and third devices on the top layer.
