Range

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 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. A faster maximum current limit

response time is the only difference between the TPS2223A, TPS2224A, and TPS2226A and the TPS2223,

TPS2224, and TPS2226.

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 TPS2223A does not support 12-V switching to VPP. For the most current package and ordering information,

see the Package Option Addendum at the end of this document, or see the TI website at www.ti.com .
