3 Description

The TPS2595xx family of eFuses (integrated FET hot

swap devices) 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 current limit level can be set with a single

external resistor. It is also possible to get an accurate

sense of the output load current by measuring the

voltage drop across the current limit resistor.

Applications with particular inrush current

requirements can set the output slew rate with a

single external capacitor. Overvoltage events are

quickly limited by internal clamping circuits to a safe

fixed maximum, with no external components

required. The TPS259573 variant provides an option

to set a user-defined overvoltage cutoff threshold.

Quick output discharge function can be implemented

in the TPS2595x5 variants by connecting the OUT

pin to the QOD pin.

The devices are characterized for operation over the

temperature range of –40°C to +125°C.
