TPS2052C Power-Distribution Switches

The TPS20xxC and TPS20xxC-2 dual powerdistribution switch family is intended for applications such as USB where heavy capacitive loads and short-circuits may be encountered. This family offers multiple devices with fixed current-limit thresholds for applications between 0.5 A and 2 A. The TPS20xxC and TPS20xxC-2 dual family limits the output current to a saf.
