description

The TPS2205 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, 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 a specific card.

The TPS2205 is backward compatible with the TPS2201, except that there is no V_DDconnection at pin 25. Bias current is derived from either the 3.3-V input pin or the 5-V input pin. The TPS2205 also eliminates the APWR_GOOD and BPWR_GOOD pins of the TPS2201.

The TPS2205 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.

End equipment for the TPS2205 includes notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras, handiterminals, and bar-code scanners
