PC Card sockets. 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 r DS(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. Like the TPS2214 and TPS2214A and the TPS2216 and TPS2216A, this family of devices supports independent VPP/VCC switching; however, the standby and interface-mode pins are not supported. Shutdown mode is now supported independently on SHDN as well as in the serial interface. Optimized for lower power implementation, the TPS2223 does not support 12-V switching to VPP.
