3 Description
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.
