Description

General part information

TPS2205 Series

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™ 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.

The TPS2205 is backward compatible with the TPS2201, except that there is no VDDconnection. 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.
