The TPS25946xx family of eFuses 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, making it well suited for USB OTG (On-The-Go) applications.

Output slew rate and inrush current can be adjusted using a single external capacitor. Loads are protected from input overvoltage conditions by cutting off the output if input exceeds an adjustable overvoltage threshold. The devices respond to output overload by actively limiting the current. The output current limit threshold as well as the transient overcurrent blanking timer are user adjustable. The current limit control pin also functions as an analog load current monitor.

The devices are available in a 2-mm × 2-mm, 10-pin HotRod QFN package for improved thermal performance and reduced system footprint.

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