TPS259573DSGR 2.7-V to 18-V, 34mΩ, 0.5-4A eFuse with over voltage protection in small WSON package
The TPS2595xx family of eFuses (integrated FET hot swap devices) is a highly integratedcircuit protection and power management solution in a small package. The devices provide multipleprotection 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 alsopossible to get an accurate sense of the output load current by measuring the voltage drop acrossthe current limit resistor. Applications with particular inrush current requirements can set theoutput slew rate with a single external capacitor. Overvoltage events are quickly limited byinternal clamping circuits to a safe fixed maximum, with no external components required. TheTPS259573 variant provides an option to set a user-defined overvoltage cutoff threshold.
Quick output discharge function can be implemented in the TPS2595x5 variants byconnecting the OUT pin to the QOD pin.
The devices are characterized for operation over the temperature range of –40°C to+125°C.
