Description
The TPS20xxC and TPS20xxC-2 power-distribution switch family is intended for applications, such as USB, where heavy capacitive loads and short circuits are likely to be encountered. This family offers multiple devices with fixed current-limit thresholds for applications from 0.5 A to 2 A.
The TPS20xxC and TPS20xxC-2 family 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.
