TPS2001D Current-Limited, Power Distribution Switches

 

描述

The TPS2001D power-distribution switch is intended for applications where heavy capacitive loads and short circuits are likely to be encountered, such as USB.

The TPS2001D limits the output current to a safe level by operating in a constant-current mode when the output load exceeds the current limit threshold. This provides a predictable fault current under all conditions. The fast overload response time eases the burden on the main 5-V supply to provide regulated power when the output is shorted. The power-switch rise and fall times are controlled to minimize current surges during turnon and turnoff.
