1 / 28 page TPS2211A SINGLESLOT PC CARD POWER INTERFACE SWITCH FOR PARALLEL PCMCIA CONTROLLERS SLVS282B − SEPTEMBER 2000 − REVISED JULY 2005 1 WWW.TI.COM D Fully Integrated VCC and Vpp Switching for Single-Slot PC Card Interface D Low rDS(on) (70-mΩ 5-V VCC Switch and 3.3-V VCC Switch) D Compatible With Industry-Standard Controllers D 3.3-V Low-Voltage Mode D Meets PC Card Standards D 12-V Supply Can Be Disabled Except During 12-V Flash Programming D Short-Circuit and Thermal Protection D Space-Saving 16-Pin SSOP (DB) and 20-Pin HTSSOP (PWP) D Compatible With 3.3-V, 5-V, and 12-V PC Cards D Break-Before-Make Switching description The TPS2211A PC Card power-interface switch provides an integrated power-management solu- tion for a single PC Card. 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, using the Texas Instruments LinBiCMOS process. 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. Current-limit reporting can help the user isolate a system fault to the PC Card. controllers. The current-limiting feature eliminates the need for fuses, which reduces component count and improves reliability. Current-limit reporting can help the user isolate a system fault to the PC Card. The TPS2211A features a 3.3-V low-voltage mode that allows for 3.3-V switching without the need for 5 V. Bias power can be derived from either the 3.3-V or 5-V inputs. This facilitates low-power system designs such as sleep mode and pager mode where only 3.3 V is available. End equipment for the TPS2211A includes notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras, and bar-code scanners.
