DAP PACKAGE  
(TOP VIEW)  
The TPS2205 PC Card power-interface switch  
provides an integrated power-management  
solution for two PC Cards. All of the discrete  
power MOSFETs, a logic section, current limiting,  
and thermal protection for PC Card control are  
combined on a single integrated circuit (IC), using  
the Texas Instruments LinBiCMOSprocess.  
The circuit allows the distribution of 3.3-V, 5-V,  
and/or 12-V card power, and is compatible with  
many PCMCIA controllers. The current-limiting  
feature eliminates the need for fuses, which  
reduces component count and improves  
reliability.

The TPS2205 is backward compatible with the

TPS2201, except that there is no V connection.

Bias current is derived from either the 3.3-V input  
pin or the 5-V input pin. The TPS2205 also  
eliminates the APWR_GOOD and BPWR_GOOD  
pins of the TPS2201.  
3.3V  
NC − No internal connection  
The TPS2205 features a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5 V. This  
facilitates low-power system designs such as sleep mode and pager mode where only 3.3 V is available.  
End equipment for the TPS2205 includes notebook computers, desktop computers, personal digital assistants  
(PDAs), digital cameras, and bar-code scanners.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
