PRODUCTION DATA.
The TPS25982 device is an integrated 15-A eFuse that is typically used for hot-swap and power rail protection applications. It operates from 2.7 V to 24 V with adjustable overcurrent and undervoltage protection. It also provides optional overvoltage with various fixed internal thresholds. The device aids in controlling the inrush current and has the flexibility to configure the number of auto-retries and retry delay. The adjustable overcurrent blanking timer provides the functionality to allow transient overcurrent pulses without limiting or tripping. These devices protect source, load and internal MOSFET from potentially damaging events in systems such as Server standby rails, PCIe cards, SSDs, HDDs, Optical Modules, Routers and Switches.
The following design procedure can be used to select the supporting component values based on the application requirement. Additionally, a spreadsheet design tool TPS25982xx Design Calculator is available in the web product folder.
