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 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 V_DD connection.
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, and bar-code scanners.
