The TPS2223, TPS2224 and TPS2226 Card-
Bus power-interface switches provide an
integrated power-management solution for two

† _{Pin 7 and 20 are NC for TPS2223.}
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. See the available options table for
pin-compatible device information.
