Texas Instruments TPS2041/TPS2051 Power-Distribution Switches Datasheet
The TPS2041 and TPS2051 are N-channel MOSFET high-side power switches designed for applications with heavy capacitive loads and short circuits. They feature an internal charge pump to minimize current surges and operate from supplies as low as 2.7 V. The devices are available in 8-pin SOIC and PDIP packages.

Questions answered in these manuals
What is the minimum input voltage for operation?
The charge pump allows operation from supplies as low as 2.7 V.
From: Texas Instruments TPS2041/TPS2051 Power-Distribution Switches Datasheet
How does the device protect against short circuits?
It switches into a constant-current mode and pulls the overcurrent logic output low.

What is the purpose of the TPS2041 and TPS2051 devices?
They are power‑distribution switches intended for applications where heavy capacitive loads and short circuits are likely to be encountered.
How does over‑current protection work?
When an over‑current or over‑temperature condition occurs, the device switches to a constant‑current mode and asserts an active‑low OC output.
What is the maximum continuous current the TPS2041/2051 can handle?
Each switch can continuously source up to 500 mA.
