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(TM) process. The circuit allows the distribution of 3.3-V, 5-V, and/or 12-V card power by means of the P2 C (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 V DD 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.
