  PC Card Power Management Techniques – Design Note 76
  Tim Skovmand
  Most portable computers have sockets built in to accept
  small PC cards for use as extended memories, data/fax
  modems, network interfaces, wireless communicators,
  etc. The Personal Computer Memory Card International
  Association (PCMCIA) has released specifications, 1.0
  and 2.0, which outline the general voltage and power
  requirements for these cards.
  Power is provided by the host computer to the PC card
  through the card socket via the main VCC supply pin(s)
  and the VPP programming supply pins. Both supplies
  can be switched to different voltages to accommodate
  a wide range of card types and applications.
  The VCC supply can be switched from 5V to 3.3V and
  must be capable of supplying upwards of 1A for short
  periods of time and hundreds of milliamps continuously. Three low resistance MOSFET switches are typically used to select the card VCC power as shown in
  Figure 1. The LTC В®1165 inverting triple MOSFET driver
  accepts active-low logic commands directly from a
  common PCMCIA controller and generates gate drive
  voltages above the positive rail to fully enhance low
  5V RDS(ON) N-channel MOSFET switches. Two back-to-back
  MOSFET switches, Q2 and Q3, isolate the parasitic …
