3 Description
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 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 (during startup)
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 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.
