Texas Instruments TPS2047/TPS2057 Triple Current-Limited Power-Distribution Switches Datasheet
The TPS2047 and TPS2057 are triple power-distribution switches designed for applications involving heavy capacitive loads and potential short circuits. Each device incorporates three 135-mΩ N-channel MOSFET high-side power switches in a single package, controlled by logic enable inputs compatible with both 5-V and 3-V logic levels.

Questions answered in these manuals
What is the typical rise time of the output?
The rise and fall times are typically in the 2-ms to 4-ms range.
From: Texas Instruments TPS2047/TPS2057 Triple Current-Limited Power-Distribution Switches Datasheet
How does the device protect against overcurrent?
When an overload or short circuit is encountered, the driver reduces gate voltage to switch the output into a constant current mode.
