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.
