description  
The TPS2206 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 LinBiCMOS process.  
The circuit allows the distribution of 3.3-V, 5-V,

The TPS2206 is backward compatible with the  
TPS2202 and TPS2202A, except that there is no  
3.3V  
V
connection. Bias current is derived from  
DD  
either the 3.3-V input pin or the 5-V input pin. The  
TPS2206 also eliminates the APWR_GOOD and  
BPWR_GOOD pins of the TPS2202 and  
TPS2202A.  
NC – No internal connection  
The TPS2206 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.
