DESCRIPTION
The TPS2231 and TPS2236 ExpressCard power interface switches provide the total power management solution
required by the ExpressCard specification. The TPS2231 and TPS2236 ExpressCard power interface switches
distribute 3.3 V, AUX, and 1.5 V to the ExpressCard socket. Each voltage rail is protected with integrated
current-limiting circuitry.
The TPS2231 supports systems with single-slot ExpressCard|34 or ExpressCard|54 sockets. The TPS2236
supports systems with dual-slot ExpressCard sockets.
End equipment for the TPS2231 and TPS2236 include notebook computers, desktop computers, personal digital
assistants (PDAs), and digital cameras.
