The TPS2211 PC Card power-interface switch provides an integrated power-management solution for interface to PC cards. It features a single slot parallel control interface that is compatible with PC card controllers from Texas Instruments, Cirrus Logic, and Intel. The TPS2211 includes all of the discrete power MOSFETs, a logic section, current limiting, thermal protection, and a 3.3-V low voltage mode required for PC Card applications, all combined in a single integrated circuit. This device allows the distribution of 3.3-V, 5-V, and/or 12-V power to PC cards. The current limiting and thermal shutdown features eliminate the need for discrete components such as fuses. These features improve reliability and reduce component count. Current limit reporting can help the user isolate a power fault to a defective PC Card.

The TPS2211 is a high performance version of Texas Instruments TPS2205 parallel dual slot power interface device. Like the predecessor, the TPS2211 does not require a VDD connection. Bias current is derived from either the 3.3-V or 5-V input pins. This power switch is optimized for the best cost and rDS(on) performance for this application, while fully meeting the power requirements of the PCMCIA specification. Both the 3.3-V and 5-V switch are capable of driving 1 A and maintain the required voltage regulation.

Like the TPS2205, the TPS2211 features a 3.3 V low voltage mode of operation that allows 3.3-V switching without the need for 5-V or 12-V. This facilitates low power system designs such as sleep mode or pager mode where only 3.3-V is available or required. This device is available in a 16-pin SSOP (DB).
