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,

(PCMCIA Peripheral-Control) Texas Instruments

nonproprietary serial interface. The current-limiting

feature eliminates the need for fuses, which

reduces component count and improves reliability.

The TPS2206 is backward compatible with the

TPS2202 and TPS2202A, except that there is no

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.

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.
