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.
