2.7-V to 16-V, 10-A, 6-mΩ eFuse with transient overcurrent blanking timer

The TPS25981xx 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.

Output slew rate and inrush current

can be adjusted using one 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 (during start-up) or breaking the circuit (during steady-state). The

overcurrent protection 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 2mm ×

2mm, 10-pin HotRod™ QFN package for

improved thermal performance and reduced system footprint.

The devices are characterized for

operation over a junction temperature range from –40°C to +125°C.
