The TPS20xxC and TPS20xxC-2 power distribution switch families are used in applications such as USB where high capacitive loads and short circuits may be encountered. This family of products offers a variety of devices with fixed current limit thresholds for applications between 0.5A and 2A.
When the output load exceeds the current limit threshold, the TPS20xxC and TPS20xxC-2 limit the output current to a safe level by operating in constant current mode. This provides a predictable fault current under all conditions. The fast overload response time relieves the burden of providing regulated power from the main 5V supply when the output is shorted. To greatly reduce current surges during turn-on and turn-off, the number of rises and falls of the power switch is controlled.
