DESCRIPTION
The TPS2223A, TPS2224A, and TPS2226A Card Bus™ power-interface switches provide an integrated
power-management solution for two PC Card sockets. The TPS2220A is single-slot option for this family of
devices. These devices allow the controlled distribution of 3.3 V, V, and to each card slot. The
current-limiting and thermal-protection features eliminate the need for fuses. Current-limit reporting helps the user
isolate 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. 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. See the available options table for pin-compatible device
information.
