power-distribution switch family is intended for applications such as USB where heavy capacitive
loads and short circuits are likely to be encountered. The device can continuously deliver up to
1 A output current.
The TPS2065D 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.
