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 LinBiCMOSprocess.
The circuit allows the distribution of 3.3-V, 5-V,
and/or 12-V card power by means of the P2C
(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
VDD 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.

description (continued)
The TPS2206 incorporates a reset function, selectable by one of two inputs, to help alleviate system errors. The
reset function enables PC Card initialization concurrent with host platform initialization, allowing a system reset.
Reset is accomplished by grounding the VCC and Vpp (flash-memory programming voltage) outputs, which
discharges residual card voltage.
End equipment for the TPS2206 includes notebook computers, desktop computers, personal digital assistants
(PDAs), digital cameras and bar-code scanners.
