The TPS25984x is a high-current eFuse that is typically used for power rail protection applications. The device operates from 4.5 V to 16 V with input overvoltage and adjustable undervoltage protection. The device provides the ability to control inrush current and offers protection against overcurrent and short-circuit conditions. The device can be used in a variety of systems such as server motherboards, add-on cards, graphics cards, accelerator cards, enterprise switches, routers, and so forth. The design procedure explained in the subsequent sections can be used to select the supporting component values based on the application requirements. Additionally, a spreadsheet design tool TPS25984x Design Calculator is available on request.
