TPS25946xx 2.7V to 23V 5.5A eFuse Texas Instruments TPS25946xx 2.7V to 23V 5.5A eFuse is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using very few external components and are a robust defense against overloads, short-circuits, voltage surges, and excessive inrush current. With integrated back-to-back FETs, the device allows bi-directional current flow during ON state while blocking current flow in both directions during OFF state. This feature makes it well suited for USB OTG (On-The-Go) applications.
