The TPS2223A, TPS2224A, and TPS2226A CardBus™ power-interface switches provide an integrated power-management soluTIon for two PC Card sockets. The TPS2220A is a single-slot opTIon for this family of devices. These devices allow the controlled distribuTIon of 3.3 V, 5 V, and 12 V to each card slot. The current-limiTIng and thermal-protection features eliminate the need for fuses. Current-limit reporting helps the user isolate a system fault. The switch rDS(on) and current-limit values have been set for the peak and average current requirements stated in the PC Card specification, and optimized for cost. A faster maximum current limit response time is the only difference between the TPS2223A, TPS2224A, and TPS2226A and the TPS2223, TPS2224, and TPS2226.
