TPS2231 ExpressCard 单电源接口开关
TPS2231 描述
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
