描述 Description

The TPS25961eFuse(integrated FET hot-swap device) is a highly integrated circuit protection and power management solution in a small package. The device provides multiple protection modes using very few external components and is a robust defense against overloads, short-circuits, voltage surges, and excessive inrush current. Output current limit level can be set with a single external resistor. Inrush current is managed using output slew rate control internally. To protect an input overvoltage condition, the device provides an option to externally set a user-defined overvoltage cutoff threshold or use a fixed internal threshold.

The devices are characterized for operation over a junction temperature range of –40 °C to +125 °C.
