US12231 Datasheet


The UTC US12231 ExpressCardTM  power interface switches
are designed to meet the ExpressCardTM specification. The UTC US12231
 distribute 3.3V, AUX, and 1.5V to the single-slot ExpressCard|34 or ExpressCard|54 sockets.
Each voltage rail is protected with integrated current-limiting circuitry, other functions include
 thermal protection circuit turns off switches to prevent device from damage when heavy overloads
or short circuits,
The UTC US12231 can use in notebook computers, desktop computers, PDAs, and digital cameras.
* Meets the ExpressCardTM standard (ExpressCard|34 or ExpressCard|54)
Compliant with the ExpressCardTM compliance checklists
Fully satisfies the ExpressCardTM implementation guidelines
Supports systems with WAKE function
TTL-Logic compatible inputs
Short circuit and thermal protection
-40°C ~ 85°C ambient operating temperature range
