Using the TPS2231 ExpressCard Power Switch/Controller

An ExpressCard™ module is an add-in card with a serial interface based on PCI Express™ and/or Universal Serial Bus (USB) technologies. Power to the ExpressCard slot is provided by the host system as defined in the ExpressCard Standard. The TPS2231 ExpressCard power switch/controller simplifies the host design by providing a fully integrated solution for controlling power to an ExpressCard slot.
