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, and/or 12-V card power by means of the P2C (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 VDD connection. Bias current is derived from 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.
