description

The TPS2223, TPS2224 and TPS2226 Card-

Bus

 power-interface switches provide an

integrated power-management solution for two

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

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.
