The TPS2211A PC Card power-interface switch  
provides an integrated power-management solu-  
tion for a single PC Card. 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, using the  
Texas Instruments LinBiCMOS process. The  
circuit allows the distribution of 3.3-V, 5-V, and/or  
AVPP

Must be tied together externally as close to the device as  
possible.

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. Current-limit reporting can help the user isolate a system fault to the PC Card. controllers.  
The current-limiting feature eliminates the need for fuses, which reduces component count and  
improves reliability. Current-limit reporting can help the user isolate a system fault to the PC Card.  
The TPS2211A features a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5 V. Bias  
power can be derived from either the 3.3-V or 5-V inputs. This facilitates low-power system designs such as  
sleep mode and pager mode where only 3.3 V is available.
