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 LinBiCMOSprocess.
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 VDD 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.
