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.

    ... TPS2236 SLVS536J – JULY 2004 – REVISED SEPTEMBER This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications ...
