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
