Application Information

The TPS25961 device is an integrated eFuse that is typically used for input hot-swap and power rail protection applications for systems such as energy meters, set-top boxes, building automation and adapter input protection. The device operates from 2.7-V to 19-V with adjustable current limit, overvoltage and undervoltage protection. The device aids in controlling the inrush current and provides current limiting during overload conditions.

The design procedure explained in the subsequent sections can be used to select the supporting component values based on the application requirement. Additionally, a spreadsheet design tool, TPS25961 Design Calculator, is available in the web product folder.
