description
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™ process.
The circuit allows the distribution of 3.3-V, 5-V,
and/or 12-V card power by means of the P
2
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.
