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 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.

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.
