The Texas Instruments TPS2231MRGPR-2 is an ExpressCard power interface switch designed to provide the necessary power management solution for the ExpressCard specification. It supports systems with single-slot ExpressCard|34 or ExpressCard|54 sockets.
This device distributes 3.3V, AUX, and 1.5V to the ExpressCard socket, with each voltage rail protected by integrated current-limiting circuitry. Key electrical specifications include a maximum continuous current of 1.3A, a typical Rds On of 45mOhm, and an OFF-state leakage current of 1µA. It features Power Good and Status Flag outputs.
The TPS2231MRGPR-2 operates within an ambient temperature range of -40°C to 85°C. It is available in a 20-QFN (4x4) package with a surface mount type and an exposed pad for enhanced thermal performance. The switch type is specifically an ExpressCard Switch, compliant with relevant standards and implementation guidelines.
Applications for this power interface switch include notebook computers, desktop computers, personal digital assistants (PDAs), digital cameras, and TV/set-top boxes that utilize the ExpressCard interface.
